https://github.com/huggingface/datasets/issues/708 | Datasets performance slow? - 6.4x slower than in memory dataset | Facing a similar issue here. My model using SQuAD dataset takes about 1h to process with in memory data and more than 2h with datasets directly. | I've been very excited about this amazing datasets project. However, I've noticed that the performance can be substantially slower than using an in-memory dataset.
Now, this is expected I guess, due to memory mapping data using arrow files, and you don't get anything for free. But I was surprised at how much slower.
For example, in the `yelp_polarity` dataset (560000 datapoints, or 17500 batches of 32), it was taking me 3:31 to just get process the data and get it on the GPU (no model involved). Whereas, the equivalent in-memory dataset would finish in just 0:33.
Is this expected? Given that one of the goals of this project is also accelerate dataset processing, this seems a bit slower than I would expect. I understand the advantages of being able to work on datasets that exceed memory, and that's very exciting to me, but thought I'd open this issue to discuss.
For reference I'm running a AMD Ryzen Threadripper 1900X 8-Core Processor CPU, with 128 GB of RAM and an NVME SSD Samsung 960 EVO. I'm running with an RTX Titan 24GB GPU.
I can see with `iotop` that the dataset gets quickly loaded into the system read buffers, and thus doesn't incur any additional IO reads. Thus in theory, all the data *should* be in RAM, but in my benchmark code below it's still 6.4 times slower.
What am I doing wrong? And is there a way to force the datasets to completely load into memory instead of being memory mapped in cases where you want maximum performance?
At 3:31 for 17500 batches, that's 12ms per batch. Does this 12ms just become insignificant as a proportion of forward and backward passes in practice, and thus it's not worth worrying about this in practice?

| 19 | Datasets performance slow? - 6.4x slower than in memory dataset
I've been very excited about this amazing datasets project. However, I've noticed that the performance can be substantially slower than using an in-memory dataset.
Now, this is expected I guess, due to memory mapping data using arrow files, and you don't get anything for free. But I was surprised at how much slower.
For example, in the `yelp_polarity` dataset (560000 datapoints, or 17500 batches of 32), it was taking me 3:31 to just get process the data and get it on the GPU (no model involved). Whereas, the equivalent in-memory dataset would finish in just 0:33.

https://github.com/huggingface/datasets/issues/708 | Datasets performance slow? - 6.4x slower than in memory dataset | Great! Thanks a lot.
I did a test using `map(..., keep_in_memory=True)` and also a test using in-memory only data.
```python
features = dataset.map(tokenize, batched=True, remove_columns=dataset['train'].column_names)
features.set_format(type='torch', columns=['input_ids', 'token_type_ids', 'attention_mask'])
features_in_memory = dataset.map(tokenize, batched=True, keep_in_memory=True, remove_columns=dataset['train'].column_names)
features_in_memory.set_format(type='torch', columns=['input_ids', 'token_type_ids', 'attention_mask'])
in_memory = [features['train'][i] for i in range(len(features['train']))]
```
For using the features without any tweak, I got **1min17s** for copying the entire DataLoader to CUDA:
```
%%time
for i, batch in enumerate(DataLoader(features['train'], batch_size=16, num_workers=4)):
batch['input_ids'].to(device)
```
For using the features mapped with `keep_in_memory=True`, I also got **1min17s** for copying the entire DataLoader to CUDA:

batch['input_ids'].to(device)

Thanks for all your great work.
Great! Thanks a lot.
I did a test using `map(..., keep_in_memory=True)` and also a test using in-memory only data.
```python
features = dataset.map(tokenize, batched=True, remove_columns=dataset['train'].column_names)
features.set_format(type='torch', columns=['input_ids', 'token_type_ids', 'attention_mask'])
features_in_memory = dataset.map(tokenize, batched=True, keep_in_memory=True, remove_columns=dataset['train'].column_names)
features_in_memory.set_format(type='torch', columns=['input_ids', 'token_type_ids', 'attention_mask'])
in_memory = [features['train'][i] for i in range(len(features['train']))]
```
For using the features without any tweak, I got **1min17s** for copying the entire DataLoader to CUDA:
```
%%time
for i, batch in enumerate(DataLoader(features['train'], batch_size=16, num_workers=4)):
batch['input_ids'].to(device)
```
For using the features mapped with `keep_in_memory=True`, I also got **1min17s** for copying the entire DataLoader to CUDA:
```
%%time
for i, batch in enumerate(DataLoader(features_in_memory['train'], batch_size=16, num_workers=4)):
batch['input_ids'].to(device)
```
And for the case using every element in memory, converted from the original dataset, I got **12.5s**:
```
%%time
for i, batch in enumerate(DataLoader(in_memory, batch_size=16, num_workers=4)):
batch['input_ids'].to(device)
```
Taking a closer look in my SQuAD code, using a profiler, I see a lot of calls to `posix read` api. It seems that it is really reliying on disk, which results in a very high train time. |

I am missing something? I think it is something related to size, and not disk or in-memory. | I've been very excited about this amazing datasets project. However, I've noticed that the performance can be substantially slower than using an in-memory dataset.

For example, in the `yelp_polarity` dataset (560000 datapoints, or 17500 batches of 32), it was taking me 3:31 to just get process the data and get it on the GPU (no model involved). Whereas, the equivalent in-memory dataset would finish in just 0:33.

For reference, my conda environment is [here](https://gist.github.com/05b6101518ff70ed42a858b302a0405d)
Once again, I'm very excited about this library, and how easy it is to load datasets, and to do so without worrying about system memory constraints.
Thanks for all your great work.
My fault! I had not seen the `dataloader_num_workers` in `TrainingArguments` ! Now I can parallelize and go fast! Sorry, and thanks. |

1. I did fork the repository and clone the same on my local system.
2. Then learnt about how we can publish our package on pypi.org. Also, found some instructions on same in setup.py documentation.
3. Then I Perplexity document link that you shared above. I created a colab link from there keep both tensorflow and pytorch means a mixed option and tried to run it in colab but I encountered no errors at a point where you mentioned. Can you help me to figure out the issue.

Thanks for reporting :)
Indeed this is an issue on the `datasets` side.
I'm creating a PR | ## Environment info
<!-- You can run the command `transformers-cli env` and copy-and-paste its output below.
Don't forget to fill out the missing fields in that output! -->
- `transformers` version: 3.3.1 (installed from master)
- `datasets` version: 1.0.2 (installed as a dependency from transformers)
- Platform: Linux-4.15.0-118-generic-x86_64-with-debian-stretch-sid
- Python version: 3.7.9
I'm testing my own text classification dataset using [this example](https://github.com/huggingface/transformers/tree/master/examples/text-classification#run-generic-text-classification-script-in-tensorflow) from transformers. The dataset is split into train / dev / test, and in csv format, containing just a text and a label columns, using comma as sep. Here's a sample:
```

```
However, @Santosh-Gupta reported in #7351 that he had the exact same problem using the ChemProt dataset. His colab notebook is referenced in the following section.
## To reproduce
Steps to reproduce the behavior:
1. Created a new conda environment using conda env -n transformers python=3.7
2. Cloned transformers master, `cd` into it and installed using pip install --editable . -r examples/requirements.txt
3. Installed tensorflow with `pip install tensorflow`
3. Ran `run_tf_text_classification.py` with the following parameters:
```
--train_file <DATASET_PATH>/train.csv \
--dev_file <DATASET_PATH>/dev.csv \
--test_file <DATASET_PATH>/test.csv \
--label_column_id 1 \
--model_name_or_path neuralmind/bert-base-portuguese-cased \
--output_dir <OUTPUT_PATH> \
--num_train_epochs 4 \
--per_device_train_batch_size 4 \
--per_device_eval_batch_size 4 \
--do_train \
--do_eval \
--do_predict \
--logging_steps 1000 \
--evaluate_during_training \
--save_steps 1000 \
--overwrite_output_dir \
--overwrite_cache
```
I have also copied [@Santosh-Gupta 's colab notebook](https://colab.research.google.com/drive/11APei6GjphCZbH5wD9yVlfGvpIkh8pwr?usp=sharing) as a reference.

TypeError: '<' not supported between instances of 'NamedSplit' and 'NamedSplit'
```
## Expected behavior
Should be able to run the text-classification example as described in [https://github.com/huggingface/transformers/tree/master/examples/text-classification#run-generic-text-classification-script-in-tensorflow](https://github.com/huggingface/transformers/tree/master/examples/text-classification#run-generic-text-classification-script-in-tensorflow)
Originally opened this issue at transformers' repository: [https://github.com/huggingface/transformers/issues/7535](https://github.com/huggingface/transformers/issues/7535). @jplu instructed me to open here, since according to [this](https://github.com/huggingface/transformers/issues/7535#issuecomment-702778885) evidence, the problem is from datasets.
Thanks! | 19 | TypeError: '<' not supported between instances of 'NamedSplit' and 'NamedSplit'
## Environment info
<!-- You can run the command `transformers-cli env` and copy-and-paste its output below.
Don't forget to fill out the missing fields in that output! -->
- `transformers` version: 3.3.1 (installed from master)
- `datasets` version: 1.0.2 (installed as a dependency from transformers)
- Platform: Linux-4.15.0-118-generic-x86_64-with-debian-stretch-sid
- Python version: 3.7.9
I'm testing my own text classification dataset using [this example](https://github.com/huggingface/transformers/tree/master/examples/text-classification#run-generic-text-classification-script-in-tensorflow) from transformers. The dataset is split into train / dev / test, and in csv format, containing just a text and a label columns, using comma as sep. Here's a sample:
```
text,label

```
However, @Santosh-Gupta reported in #7351 that he had the exact same problem using the ChemProt dataset. His colab notebook is referenced in the following section.
## To reproduce
Steps to reproduce the behavior:
1. Created a new conda environment using conda env -n transformers python=3.7
2. Cloned transformers master, `cd` into it and installed using pip install --editable . -r examples/requirements.txt
3. Installed tensorflow with `pip install tensorflow`
3. Ran `run_tf_text_classification.py` with the following parameters:
```
--train_file <DATASET_PATH>/train.csv \
--dev_file <DATASET_PATH>/dev.csv \
--test_file <DATASET_PATH>/test.csv \
--label_column_id 1 \
--model_name_or_path neuralmind/bert-base-portuguese-cased \
--output_dir <OUTPUT_PATH> \
--num_train_epochs 4 \
--per_device_train_batch_size 4 \
--per_device_eval_batch_size 4 \
--do_train \
--do_eval \
--do_predict \
--logging_steps 1000 \
--evaluate_during_training \
--save_steps 1000 \
--overwrite_output_dir \
--overwrite_cache
```
I have also copied [@Santosh-Gupta 's colab notebook](https://colab.research.google.com/drive/11APei6GjphCZbH5wD9yVlfGvpIkh8pwr?usp=sharing) as a reference.

https://github.com/huggingface/datasets/issues/687 | `ArrowInvalid` occurs while running `Dataset.map()` function | Hi !
This is because `encode` expects one single text as input (str), or one tokenized text (List[str]).
I believe that you actually wanted to use `encode_batch` which expects a batch of texts.
However this method is only available for our "fast" tokenizers (ex: BertTokenizerFast).
BertJapanese is not one of them unfortunately and I don't think it will be added for now (see https://github.com/huggingface/transformers/pull/7141)...
cc @thomwolf for confirmation.
Therefore what I'd suggest for now is disable batching and process one text at a time using `encode`.
Note that you can make it faster by using multiprocessing:
```python
num_proc = None # Specify here the number of processes if you want to use multiprocessing. ex: num_proc = 4
encoded = train_ds.map(
lambda example: {'tokens': t.encode(example['title'], max_length=1000)}, num_proc=num_proc
)

https://github.com/huggingface/datasets/issues/687 | `ArrowInvalid` occurs while running `Dataset.map()` function | Thank you very much for the kind and precise suggestion!
I'm looking forward to seeing BertJapaneseTokenizer built into the "fast" tokenizers.
I tried `map` with multiprocessing as follows, and it worked!
```python
# There was a Pickle problem if I use `lambda` for multiprocessing
def encode(examples):
return {'tokens': t.encode(examples['title'], max_length=1000)}
num_proc = 8
encoded = train_ds.map(encode, num_proc=num_proc)
```

Thank you very much for the kind and precise suggestion!
I'm looking forward to seeing BertJapaneseTokenizer built into the "fast" tokenizers.
I tried `map` with multiprocessing as follows, and it worked!
```python
# There was a Pickle problem if I use `lambda` for multiprocessing
def encode(examples):
return {'tokens': t.encode(examples['title'], max_length=1000)}
num_proc = 8
encoded = train_ds.map(encode, num_proc=num_proc)
```
Thank you again! |

I'm looking into your `xsum` dataset and I have several questions on that.
So here is how I loaded the data:
```

The first issue is, the instance counts donโt match what I see on [the dataset's website](https://github.com/EdinburghNLP/XSum/tree/master/XSum-Dataset#what-builds-the-xsum-dataset) (11,333 vs 11,334 for test set; 204,017 vs 204,045 for training set)

https://github.com/huggingface/datasets/issues/669 | How to skip a example when running dataset.map | Hi @xixiaoyao,
Depending on what you want to do you can:
- use a first step of `filter` to filter out the invalid examples: https://huggingface.co/docs/datasets/processing.html#filtering-rows-select-and-filter
- or directly detect the invalid examples inside the callable used with `map` and return them unchanged or even remove them at the same time if you are using `map` in batched mode.

The script is adapted from [this colab](https://colab.research.google.com/github/huggingface/datasets/blob/master/notebooks/Overview.ipynb) that presents an example of fine-tuning BertForQuestionAnswering using squad dataset. In that colab, loss works fine. When I adapt it to SST2, the loss fails to decrease as it should. I attach the adapted script below and appreciate anyone pointing out what I miss?
```python
import torch
from datasets import load_dataset
from transformers import BertForSequenceClassification
from transformers import BertTokenizerFast
# Load our training dataset and tokenizer
dataset = load_dataset("glue", 'sst2')
tokenizer = BertTokenizerFast.from_pretrained('bert-base-cased')
del dataset["test"] # let's remove it in this demo
# Tokenize our training dataset
def convert_to_features(example_batch):
encodings = tokenizer(example_batch["sentence"])
encodings.update({"labels": example_batch["label"]})
return encodings
encoded_dataset = dataset.map(convert_to_features, batched=True)
# Format our dataset to outputs torch.Tensor to train a pytorch model
columns = ['input_ids', 'token_type_ids', 'attention_mask', 'labels']
encoded_dataset.set_format(type='torch', columns=columns)
# Instantiate a PyTorch Dataloader around our dataset

def collate_fn(examples):
return tokenizer.pad(examples, return_tensors='pt')
dataloader = torch.utils.data.DataLoader(encoded_dataset['train'], collate_fn=collate_fn, batch_size=8)
# Now let's train our model
device = 'cuda' if torch.cuda.is_available() else 'cpu'
# Let's load a pretrained Bert model and a simple optimizer

batch.to(device)

https://github.com/huggingface/datasets/issues/665 | runing dataset.map, it raises TypeError: can't pickle Tokenizer objects | Hi !
It works on my side with both the LongFormerTokenizer and the LongFormerTokenizerFast.
Which version of transformers/datasets are you using ? | I load squad dataset. Then want to process data use following function with `Huggingface Transformers LongformerTokenizer`.
```
def convert_to_features(example):
# Tokenize contexts and questions (as pairs of inputs)
input_pairs = [example['question'], example['context']]
encodings = tokenizer.encode_plus(input_pairs, pad_to_max_length=True, max_length=512)
context_encodings = tokenizer.encode_plus(example['context'])
# Compute start and end tokens for labels using Transformers's fast tokenizers alignement methodes.
# this will give us the position of answer span in the context text
start_idx, end_idx = get_correct_alignement(example['context'], example['answers'])
start_positions_context = context_encodings.char_to_token(start_idx)
end_positions_context = context_encodings.char_to_token(end_idx-1)
# here we will compute the start and end position of the answer in the whole example
# as the example is encoded like this <s> question</s></s> context</s>
# and we know the postion of the answer in the context
# we can just find out the index of the sep token and then add that to position + 1 (+1 because there are two sep tokens)
# this will give us the position of the answer span in whole example
sep_idx = encodings['input_ids'].index(tokenizer.sep_token_id)
start_positions = start_positions_context + sep_idx + 1
end_positions = end_positions_context + sep_idx + 1
if end_positions > 512:
start_positions, end_positions = 0, 0
encodings.update({'start_positions': start_positions,
'end_positions': end_positions,
'attention_mask': encodings['attention_mask']})
return encodings
```
Then I run `dataset.map(convert_to_features)`, it raise
```

Hi !
It works on my side with both the LongFormerTokenizer and the LongFormerTokenizerFast.
Which version of transformers/datasets are you using ? |
https://github.com/huggingface/datasets/issues/665 | runing dataset.map, it raises TypeError: can't pickle Tokenizer objects | Then I guess you need to give us more informations on your setup (OS, python, GPU, etc) or a Google Colab reproducing the error for us to be able to debug this error. | I load squad dataset. Then want to process data use following function with `Huggingface Transformers LongformerTokenizer`.
```
def convert_to_features(example):
# Tokenize contexts and questions (as pairs of inputs)
input_pairs = [example['question'], example['context']]
encodings = tokenizer.encode_plus(input_pairs, pad_to_max_length=True, max_length=512)
context_encodings = tokenizer.encode_plus(example['context'])
# Compute start and end tokens for labels using Transformers's fast tokenizers alignement methodes.
# this will give us the position of answer span in the context text
start_idx, end_idx = get_correct_alignement(example['context'], example['answers'])
start_positions_context = context_encodings.char_to_token(start_idx)
end_positions_context = context_encodings.char_to_token(end_idx-1)
# here we will compute the start and end position of the answer in the whole example
# as the example is encoded like this <s> question</s></s> context</s>
# and we know the postion of the answer in the context
# we can just find out the index of the sep token and then add that to position + 1 (+1 because there are two sep tokens)
# this will give us the position of the answer span in whole example
sep_idx = encodings['input_ids'].index(tokenizer.sep_token_id)
start_positions = start_positions_context + sep_idx + 1
end_positions = end_positions_context + sep_idx + 1
if end_positions > 512:
start_positions, end_positions = 0, 0
encodings.update({'start_positions': start_positions,
'end_positions': end_positions,
'attention_mask': encodings['attention_mask']})
return encodings
```
Then I run `dataset.map(convert_to_features)`, it raise
```

Then I guess you need to give us more informations on your setup (OS, python, GPU, etc) or a Google Colab reproducing the error for us to be able to debug this error. |
https://github.com/huggingface/datasets/issues/665 | runing dataset.map, it raises TypeError: can't pickle Tokenizer objects | I have the same issue with `transformers/BertJapaneseTokenizer`.

https://github.com/huggingface/datasets/issues/665 | runing dataset.map, it raises TypeError: can't pickle Tokenizer objects | > I have the same issue with `transformers/BertJapaneseTokenizer`.
It looks like it this tokenizer is not supported unfortunately.
This is because `t.word_tokenizer.mecab` is a `fugashi.fugashi.GenericTagger` which is not compatible with pickle nor dill.
We need objects passes to `map` to be picklable for our caching system to work properly.
Here it crashes because the caching system is not able to pickle the GenericTagger.
\> Maybe you can create an issue on [fugashi](https://github.com/polm/fugashi/issues) 's repo and ask to make `fugashi.fugashi.GenericTagger` compatible with pickle ?
What you can do in the meantime is use a picklable wrapper of the tokenizer:
```python
from transformers import BertJapaneseTokenizer, MecabTokenizer
class PicklableTokenizer(BertJapaneseTokenizer):
def __getstate__(self):
state = dict(self.__dict__)
state["do_lower_case"] = self.word_tokenizer.do_lower_case
state["never_split"] = self.word_tokenizer.never_split
del state["word_tokenizer"]
return state
def __setstate__(self, state):
do_lower_case = state.pop("do_lower_case")
never_split = state.pop("never_split")
self.__dict__ = state
self.word_tokenizer = MecabTokenizer(
do_lower_case=do_lower_case, never_split=never_split)
)
t = PicklableTokenizer.from_pretrained("cl-tohoku/bert-base-japanese-whole-word-masking")
encoded = train_ds.map(lambda examples: {'tokens': t.encode(examples['title'])}, batched=True) # it works
``` | I load squad dataset. Then want to process data use following function with `Huggingface Transformers LongformerTokenizer`.
```
def convert_to_features(example):
# Tokenize contexts and questions (as pairs of inputs)
input_pairs = [example['question'], example['context']]
encodings = tokenizer.encode_plus(input_pairs, pad_to_max_length=True, max_length=512)
context_encodings = tokenizer.encode_plus(example['context'])
# Compute start and end tokens for labels using Transformers's fast tokenizers alignement methodes.
# this will give us the position of answer span in the context text
start_idx, end_idx = get_correct_alignement(example['context'], example['answers'])
start_positions_context = context_encodings.char_to_token(start_idx)
end_positions_context = context_encodings.char_to_token(end_idx-1)
# here we will compute the start and end position of the answer in the whole example
# as the example is encoded like this <s> question</s></s> context</s>
# and we know the postion of the answer in the context
# we can just find out the index of the sep token and then add that to position + 1 (+1 because there are two sep tokens)
# this will give us the position of the answer span in whole example
sep_idx = encodings['input_ids'].index(tokenizer.sep_token_id)
start_positions = start_positions_context + sep_idx + 1
end_positions = end_positions_context + sep_idx + 1
if end_positions > 512:
start_positions, end_positions = 0, 0
encodings.update({'start_positions': start_positions,
'end_positions': end_positions,
'attention_mask': encodings['attention_mask']})
return encodings
```
Then I run `dataset.map(convert_to_features)`, it raise

> I have the same issue with `transformers/BertJapaneseTokenizer`.
It looks like it this tokenizer is not supported unfortunately.
This is because `t.word_tokenizer.mecab` is a `fugashi.fugashi.GenericTagger` which is not compatible with pickle nor dill.
We need objects passes to `map` to be picklable for our caching system to work properly.
Here it crashes because the caching system is not able to pickle the GenericTagger.
\> Maybe you can create an issue on [fugashi](https://github.com/polm/fugashi/issues) 's repo and ask to make `fugashi.fugashi.GenericTagger` compatible with pickle ?
What you can do in the meantime is use a picklable wrapper of the tokenizer:
```python
from transformers import BertJapaneseTokenizer, MecabTokenizer
class PicklableTokenizer(BertJapaneseTokenizer):
def __getstate__(self):
state = dict(self.__dict__)
state["do_lower_case"] = self.word_tokenizer.do_lower_case
state["never_split"] = self.word_tokenizer.never_split
del state["word_tokenizer"]
return state
def __setstate__(self, state):
do_lower_case = state.pop("do_lower_case")
never_split = state.pop("never_split")
self.__dict__ = state
self.word_tokenizer = MecabTokenizer(
do_lower_case=do_lower_case, never_split=never_split)
)
t = PicklableTokenizer.from_pretrained("cl-tohoku/bert-base-japanese-whole-word-masking")
encoded = train_ds.map(lambda examples: {'tokens': t.encode(examples['title'])}, batched=True) # it works
``` |
https://github.com/huggingface/datasets/issues/665 | runing dataset.map, it raises TypeError: can't pickle Tokenizer objects | We can also update the `BertJapaneseTokenizer` in `transformers` as you just shown @lhoestq to make it compatible with pickle. It will be faster than asking on fugashi 's repo and good for the other users of `transformers` as well.
I'm currently working on `transformers` I'll include it in the https://github.com/huggingface/transformers/pull/7141 PR and the next release of `transformers`. | I load squad dataset. Then want to process data use following function with `Huggingface Transformers LongformerTokenizer`.

We can also update the `BertJapaneseTokenizer` in `transformers` as you just shown @lhoestq to make it compatible with pickle. It will be faster than asking on fugashi 's repo and good for the other users of `transformers` as well.
I'm currently working on `transformers` I'll include it in the https://github.com/huggingface/transformers/pull/7141 PR and the next release of `transformers`. |
https://github.com/huggingface/datasets/issues/665 | runing dataset.map, it raises TypeError: can't pickle Tokenizer objects | Thank you for the rapid and polite response!
@lhoestq Thanks for the suggestion! I've passed the pickle phase, but another `ArrowInvalid` problem occored. I created another issue #687 .

dataset = datasets.Dataset.from_dict({'field': ['a', 'b']})
print(dataset[0])
# outputs
{'field': 'a'}
# Map this dataset to create another feature called 'otherfield', which is a dictionary containing a key called 'capital'

print(dataset[0])
# output is okay

print(dataset.map(lambda example: {'otherfield': {'append_x': example['field'] + 'x'}})[0])
# printing out the first example after applying the map shows that the new key 'append_x' doesn't get added

Thanks for reporting !
It uses a temporary file to write the data.
However it looks like the temporary file is not placed in the right directory during the processing |
https://github.com/huggingface/datasets/issues/643 | Caching processed dataset at wrong folder | Well actually I just tested and the temporary file is placed in the same directory, so it should work as expected.

This seems to be on the `transformers` library side.
If you have more informations (pip env) or even better, a colab reproducing the error we can investigate. |

Could you please give me any suggestions on why this happened and how to fix it?

Hmmm so this might come from another issue...
Since it doesn't seem to be related to multiprocessing it should be easier to investigate though.
Do you have some ideas @gaceladri ? |

Thanks.
Or maybe wandb uses multiprocessing ? One process for wandb logging and one for actual training ? If this is the case then even setting `num_workers=0` would cause the process to be forked for wandb and therefore cause the memory issue. |

Thanks.
Could the bug be comming from tokenizers?
I got this warning at the terminal from my jupyter notebook:
```
huggingface/tokenizers: The current process just got forked, after parallelism has already been used. Disabling parallelism to avoid deadlocks...
To disable this warning, you can either:
- Avoid using `tokenizers` before the fork if possible
- Explicitly set the environment variable TOKENIZERS_PARALLELISM=(true | false)

My validation dataset before:
```
book_corpus_eval = load_dataset(
"bookcorpus",
"plain_text",
cache_dir="/home/ad/Desktop/bookcorpus",
split="train[98:99%]",
)
book_corpus_eval = book_corpus_eval.map(encode, batched=True)
book_corpus_eval.set_format(
type="torch", columns=["text", "input_ids", "attention_mask", "token_type_ids"]
)
**book_corpus_eval = book_corpus_eval.select([i for i in range(1500)])**
```
Maybe _selecting_ or indexing the dataset before feeding it to the trainer, do something strange.
My trainer now:
```
big_dataset = load_from_disk("/home/ad/Desktop/35percent_data.arrow/")

During training, the memory usage increased fast as the following graph and resulted in OOM before the finish of training.
Could you please give me any suggestions on why this happened and how to fix it?
Thanks.
Thanks for sharing your results.

Could you send the version of `datasets` and `pyarrow` you're using ?
Could you try to update the lib and try again ?
Or do you think you could try to reproduce it on google colab ? |

Oh I didn't know about that. Feel free to open an issue to mention that.
I guess what you can do for now is set the dataset format to numpy instead of tensorflow, and use a wrapper of the dataset that converts the numpy arrays to tf tensors.
