not being able to get wikipedia es language

Hi
I am trying to run a code with wikipedia of config 20200501.es, getting:

Traceback (most recent call last):
  File "run_mlm_t5.py", line 608, in <module>

    "\n\t`{}`".format(usage_example)
datasets.builder.MissingBeamOptions: Trying to generate a dataset using Apache Beam, yet no Beam Runner or PipelineOptions() has been provided in `load_dataset` or in the builder arguments. For big datasets it has to run on large-scale data processing tools like Dataflow, Spark, etc. More information about Apache Beam runners at https://beam.apache.org/documentation/runners/capability-matrix/
If you really want to run it locally because you feel like the Dataset is small enough, you can use the local beam runner called `DirectRunner` (you may run out of memory). 
Example of usage: 
	`load_dataset('wikipedia', '20200501.es', beam_runner='DirectRunner')`

thanks @lhoestq  for any suggestion/help 

@lhoestq  I really appreciate if you could help me providiing processed datasets, I do not really have access to enough resources to run the apache-beam and need to run the codes on these datasets. Only en/de/fr currently works, but I need all the languages more or less. thanks 

Hi @dorost1234, I think I can help you a little. I’ve processed some Wikipedia datasets (Spanish inclusive) using the HF/datasets library during recent research.

@lhoestq Could you help me to upload these preprocessed datasets to Huggingface's repositories? To be more precise, I've built datasets from the following languages using the 20201201 dumps: Spanish, Portuguese, Russian, French, Japanese, Chinese, and Turkish. Process these datasets have high costs that most of the community can't afford. I think these preprocessed datasets I have could be helpful for someone without access to high-resource machines to process Wikipedia's dumps like @dorost1234



Thank you so much @jonatasgrosman , I greatly appreciate your help with them. 
Yes, I unfortunately does not have access to a good resource and need it for my
research. I greatly appreciate @lhoestq  your help with uploading the processed datasets in huggingface datasets. This would be really helpful for some users like me with not access to high-memory GPU resources.

thank you both so much again.

Hi @dorost1234, so sorry, but looking at my files here, I figure out that I've preprocessed files using the HF/datasets for all the languages previously listed by me (Portuguese, Russian, French, Japanese, Chinese, and Turkish) except the Spanish (on my tests I've used the [wikicorpus](https://www.cs.upc.edu/~nlp/wikicorpus/) instead).

Only with the Spanish Wikipedia's dump, I had the same `KeyError: '000nbsp'` problem already reported here https://github.com/huggingface/datasets/issues/577

So nowadays, even with access to a high resource machine, you couldn't be able to get Wikipedia's Spanish data using the HF/datasets :(






Thanks a lot for the information and help. This would be great to have
these datasets.
@lhoestq <https://github.com/lhoestq>  Do you know a way I could get
smaller amount of these data like 1 GBtype of each language to deal with
computatioanl requirements? thanks

Hi ! As mentioned above the Spanish configuration have parsing issues from `mwparserfromhell`. I haven't tested with the latest `mwparserfromhell` >=0.6 though. Which version of `mwparserfromhell` are you using ?

That would be awesome ! Feel free to ping me on slack so we can put the processed wikipedia files on google storage with the other ones we've already preprocessed.

I'd suggest to copy the [wikipedia.py](https://github.com/huggingface/datasets/blob/master/datasets/wikipedia/wikipedia.py) to a new script `custom_wikipedia.py` and modify it to only download and process only a subset of the raw data files.
You can for example replace [this line](https://github.com/huggingface/datasets/blob/64e59fc45ca2134218b3e42e83fddddbe840ff74/datasets/wikipedia/wikipedia.py#L446) by:
```python
            if total_bytes >= (1 << 30):  # stop if the total amount of data is >= 1GB
                break
            else:
                xml_urls.append(_base_url(lang) + fname)
```

Then you can load your custom wikipedia dataset with
```python
load_dataset("path/to/my/custom_wikipedia.py", f"{date}.{language}")
```

Hi @lhoestq!

I'm using the latest mwparserfromhell version (0.6)

I'll ping you there 👍 

Thank you so much @jonatasgrosman  and @lhoestq  this would be a great help. I am really thankful to you both and to wonderful Huggingface dataset library allowing us to train models at scale.
