[Issue: `dolma.core.errors.DolmaFatalError` in Step 1: Run Taggers]

[yushengsu-thu]

Hello @soldni ,
I have one more question.
When I execute Step 1: Run Taggers,

dolma tag \
    --documents "wikipedia/v0/documents/*" \
    --experiment exp \ # optional; assigning a name groups taggers in a single directory
    --taggers random_number_v1 \
              cld2_en_paragraph_with_doc_score_v2 \
              ft_lang_id_en_paragraph_with_doc_score_v2 \
              char_length_with_paragraphs_v1 \
              whitespace_tokenizer_with_paragraphs_v1 \
    --processes 16   # run on 96 cores

I encounter the following issue:

Traceback (most recent call last):

dolma.core.errors.DolmaFatalError: Failed to process wikipedia/v0/documents/wiki_00.gz due to ValueError: Unable to avoid copy while creating an array as requested.
If using `np.array(obj, copy=False)` replace it with `np.asarray(obj)` to allow a copy when needed (no behavior change in NumPy 1.x).
For more details, see https://numpy.org/devdocs/numpy_2_0_migration_guide.html#adapting-to-changes-in-the-copy-keyword. 

My env:

Python 3.12.4
numpy 2.1.0
dolma 1.0.11

Is this issue coming from the processed (I used scripts/make_wikipedia.py) data wikipedia/v0/documents/wiki_00.gz or the codebases in dolma? Do you have any suggestion to mitigate or solve this issue?

[soldni]

Oh I think it's because numpy 2.x is incompatible with numpy 1.x APIs. Cutting a quick fix and a new release (dolma 1.0.12) momentarily to fix that.

@soldni thanks for your reply.
I found this issue comes from Step 0: Obtain Wikipedia processed data because of its used package wikiextractor

Now I have found a temporary solution:
set the python (from 3.12 --> 3.11) and pkgs in the following version:

Python 3.11.9
numpy 1.26.3
wikiextractor 3.0.6
dolma 1.0.11

Then, re-run the Step 0: Obtain Wikipedia

python scripts/make_wikipedia.py \
  --output wikipedia \
  --date 20231001 \
  --lang simple \
  --processes 16

and use its processed data to conduct the Step 1: Run Taggers that can mitigate this issus.
