MemoryError while creating dataset from generator
Author: simonreise
State: closed

### Describe the bug

# TL:DR

`Dataset.from_generator` function passes all of its arguments to `BuilderConfig.create_config_id`, including `generator` function itself. `BuilderConfig.create_config_id` function tries to hash all the args, which can take a large amount of time or even cause MemoryError if the dataset processed in a generator function is large enough.

Maybe we should pop `generator` from `config_kwargs_to_add_to_suffix` before hashing to avoid it.

# Full description

I have a pretty large spatial imagery dataset that is generated from two xbatcher.BatchGenerators via custom `dataset_generator` function that looks like this if simplified:
```
def dataset_generator():
    for index in samples:
        data_dict = {
            "key": index,
            "x": x_batches[index].data,
            "y":  y_batches[index].data,
        }
        yield data_dict
```
Then I use `datasets.Dataset.from_generator` to generate the dataset itself.
```
# Create dataset
ds = datasets.Dataset.from_generator(
    dataset_generator,
    features=feat,
    cache_dir=(output / ".cache"),
)
```

It works nicely with pretty small data, but if the dataset is huge and barely fits in memory, it crashes with memory error:

MemoryError:

```

</details>

Memory error is an expected type of error in such case, but when I started digging down, I found out that it occurs in a kinda unexpected place - in `create_config_id` function. It tries to hash `config_kwargs_to_add_to_suffix`, including generator function itself. 

I modified the `BuilderConfig.create_config_id` code like this to check which values are hashed and how much time it takes to hash them and ran it on a toy dataset:
```
print(config_kwargs_to_add_to_suffix)
start_time = time.time()

if all(isinstance(v, (str, bool, int, float)) for v in config_kwargs_to_add_to_suffix.values()):
    suffix = ",".join(
        str(k) + "=" + urllib.parse.quote_plus(str(v)) for k, v in config_kwargs_to_add_to_suffix.items()
    )
    if len(suffix) > 32:  # hash if too long
        suffix = Hasher.hash(config_kwargs_to_add_to_suffix)
else:
    suffix = Hasher.hash(config_kwargs_to_add_to_suffix)
end_time = time.time()

print(f"Execution time: {end_time - start_time:.4f} seconds")
print(suffix)
```

In my case the content of `config_kwargs_to_add_to_suffix` was like this:
```
{'features': {'key': Value(dtype='int64', id=None), 'x': Array3D(shape=(44, 128, 128), dtype='float32', id=None), 'y_class': Array2D(shape=(128, 128), dtype='int32', id=None)}, 'gen_kwargs': None, 'generator': <function generate_tiles.<locals>.dataset_generator at 0x00000139D10D7920>, 'split': NamedSplit('train')}
```

Also I noticed that hashing took a significant amount of time - 43.1482 seconds, while the overall function execution (with data loading, batching and saving dataset) took 2min 45s. The output of `create_config_id` is just a dataset id, so, it is inappropirately large amount of time.

But when I added `config_kwargs_to_add_to_suffix.pop("generator", None)`, the hashing took only 0.0060 seconds.

Maybe we shouldn't hash the generator function, as it can be really computationally and memory expensive.

Please, try adding `config_kwargs_to_add_to_suffix.pop("generator", None)` to `BuilderConfig.create_config_id` and then measuring how much time it takes to run 
``` 
if all(isinstance(v, (str, bool, int, float)) for v in config_kwargs_to_add_to_suffix.values()):
    suffix = ",".join(
        str(k) + "=" + urllib.parse.quote_plus(str(v)) for k, v in config_kwargs_to_add_to_suffix.items()
    )
    if len(suffix) > 32:  # hash if too long
        suffix = Hasher.hash(config_kwargs_to_add_to_suffix)
else:
    suffix = Hasher.hash(config_kwargs_to_add_to_suffix)
```
code block with and without `config_kwargs_to_add_to_suffix.pop("generator", None)`

In my case the difference was 3.3828 seconds without popping generator function and 0.0010 seconds with popping.

### Expected behavior

Much faster hashing and no MemoryErrors

Comments: Upd: created a PR that can probably solve the problem: #7514

Hi ! We need to take the generator into account for the cache. The generator is hashed to make the dataset fingerprint used by the cache. This way you can reload the Dataset from the cache without regenerating in subsequent `from_generator` calls.

Maybe instead of removing generator from the hasher input, we can let users pass their own Dataset fingerprint to `from_generator`, and if it's specified we don't need to hash anything

Upd: I successfully generated a dataset from my large geospatial data with `generator` excluded from hashing and saved it to disk without running into memory errors. So, it looks like there are no other bottlenecks in dataset generation in my case

Maybe letting users pass their own fingerprint to skip hashing can be a great solution to that issue!

@lhoestq I tried to implement user-defined dataset fingerprint in #7533 . Am I doing it right?
