Azure Python Deployment - Spacy nomodule found exception

问题

I'm using Linux App Service. I'm trying to deploy python 3.6 flask application through the Azure DevOps pipeline. It worked fine for a basic app but when I add an additional code (spacy module), it started to throw

2019-12-24T18:07:33.079953940Z     __import__(module)
2019-12-24T18:07:33.079961840Z   File "/home/site/wwwroot/application.py", line 3, in <module>

I have added the dependency modules in the requirement.txt

Flask==1.0.2
Flask-Cors==3.0.8
Flask-RESTful==0.3.7
fastai==1.0.59
numpy==1.17.4
pandas==0.25.3
requests==2.22.0
spacy==2.2.3
spacy-langdetect==0.1.2

and azurepipeline.yml

- script: |
        python -m venv antenv
        source antenv/bin/activate
        python -m pip install --upgrade pip
        pip install setup
        pip install -r requirements.txt
        python -m spacy download es
      workingDirectory: $(projectRoot)
      displayName: "Install requirements"

and my code clear_content_utility.py

import spacy
from spacy_langdetect import LanguageDetector

nlp = spacy.load('es')
nlp.add_pipe(LanguageDetector(), name='language_detector', last=True)

did anyone face the above issue? appreciate your help.

回答1:

Here is something you should do:

• Please ensure to activate the virtual environment before executing any code, also make sure to check if your installed package is actually in there in your VENV.

I would suggest you to create new VENV and try activating it.

• Secondly , you can language data has been moved to a submodule **spacy.lang** to keep thing cleaner and better organised.

  E.g. instead of using spacy.en, you now import from spacy.lang.en

    python -m spacy download en_core_web_sm
    import spacy
    nlp = spacy.load("en_core_web_sm")

ImportError: No module named 'spacy.en'

Hope it helps.
