nltk_data is absent about alpine-anaconda3

[alex-ber]

As work-around use

import pandas as pd 
import re  
import nltk
nltk.download('stopwords')
from nltk.corpus import stopwords
print(stopwords.words('english'))

Alternatively inherit from my dockerfile and add:

#nltk-data
RUN set -ex && python -m nltk.downloader -d /usr/share/nltk_data all

In place of /usr/share/nltk_data you can use any of the following path:

• '/root/nltk_data'
• '/opt/anaconda3/nltk_data'
• '/opt/anaconda3/share/nltk_data'
• '/opt/anaconda3/lib/nltk_data'
• '/usr/share/nltk_data'
• '/usr/local/share/nltk_data'
• '/usr/lib/nltk_data'
• '/usr/local/lib/nltk_data'

Note: You can set NLTK_DATA environment variable to point to your top level nltk_data folder.
However, there many pitfalls in this process, so I'm recommended to use one of the standard locations.

nltk_data takes too much place, so I've decided not to include it to my dockerfile.

If you need it, usually, you will need only some small subset of it, download it youself or by creating custom image (you will do it only once, well, per dockerfile built) o_r directly in the Python code_ (it will be re-downloading every time you will restart your docker container; every code run, check will be done, whether filles was changed). See previous post for details.
