The main content of this article is to explain "Python can not read pickle files run in cloud applications TypeError: _ _ cinit__ () how to handle", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "Python can't read pickle files and run TypeError: _ _ cinit__ () in cloud applications."

There was one I deployed to the GCP cloud to run a fast API application, and it worked well until yesterday, and I really don't know what went wrong. When I read the .pkl file, the problem seems to start on this line.

Model = pickle.load (open (os.path.join ('models',' appartementen.pkl'), 'rb'))

Retroactive:

File "pandas/_libs/internals.pyx", line 572 In pandas._libs.internals.BlockManager.__cinit__: TypeError: _ _ cinit__ () takes at least 2 positional arguments (0 given) at (/ app/src/api/util.py:25) at (/ app/src/api/main.py:8) at _ call_with_frames_removed at exec_module (: 728) at _ load_unlocked (: 677) at _ find_and_load_unlocked (: 967) at _ find_and_load At _ gcd_import (: 1006) at import_module (/ usr/local/lib/python3.7/importlib/__init__.py:127) at import_app (/ usr/local/lib/python3.7/site-packages/gunicorn/util.py:358) at load_wsgiapp (/ usr/local/lib/python3.7/site-packages/gunicorn/app/wsgiapp.py:39) at load (/ usr/local/lib/python3.7/site-packages/gunicorn/app) / wsgiapp.py:49) at wsgi (/ usr/local/lib/python3.7/site-packages/gunicorn/app/base.py:67) at load_wsgi (/ usr/local/lib/python3.7/site-packages/gunicorn/workers/base.py:144) at init_process (/ usr/local/lib/python3.7/site-packages/gunicorn/workers/base.py:119) at spawn_worker (/ usr/local/lib/python3.7/site-packages/gunicorn/arbiter.py:583)

Note that everything went well when I deployed this application locally.

My Doc file:

FROM tiangolo/uvicorn-gunicorn-fastapi:python3.7WORKDIR / appCOPY. . / COPY src. / src/COPY models. / models/RUN pip install-r requirements.txtCOPY setup.py. / CMD exec gunicorn src.api.main:app

How to deploy to the cloud to run:

Gcloud builds submit-tag gcr.io/project-id/api-timeout=3600gcloud run deploy api-image gcr.io/project-id/api-platform managed-project=project-id-region=europe-west4

Requirements.txt:

Fastapi==0.63.0google-cloud-bigquery [bqstorage,pandas] = = 1.24.0sentry_sdk==1.0.0xgboost==1.3.3scikit-learn==0.23.1shap==0.39.0matplotlib==3.4.1

I tried to use the same version according to this suggestion, but the problem still exists. Scikit-learn

Solution:

It may be that there is an incompatibility between the object version and the container version, but restoring that version is useful to me. So: pandaspandaspandas1.2.51.3.0

Pip uninstall pandaspip install pandas==1.2.5 at this point, I believe that "Python can not read pickle files run in the cloud application TypeError: _ _ cinit__ () how to deal with", might as well to the actual operation of it!
