Python无法读取pickle文件在云应用运行 TypeError: __cinit__()怎么处理?

有一个我部署到GCP云运行快速API应用程序,直到昨,它一直工作得很好,我真的不知道哪里出了问题。当我读取.pkl文件时,问题似乎从这一行开始。

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

追溯:

    File "pandas/_libs/internals.pyx", line 572, in pandas._libs.internals.BlockManager.__cinit__: TypeError: __cinit__() takes at least 2 positional arguments (0 given) at <module> (/app/src/api/util.py:25)

at spawn_worker (/usr/local/lib/python3.7/site-packages/gunicorn/arbiter.py:583)

请注意,当我在本地部署此应用程序时,一切都很顺利。

我的多克档案:

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

如何部署到云运行:

gcloud builds submit --tag gcr.io/project-id/api --timeout=3600

gcloud run deploy api --image gcr.io/project-id/api --platform managed --project=project-id --region=europe-west4

requirements.txt:

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

我尝试使用相同的版本根据这个建议,但问题仍然存在。scikit-learn

解决方法:

可能是对象的版本和容器版本之间不兼容,但恢复该版本对我有用。所以:pandaspandaspandas1.2.51.3.0

pip uninstall pandas
pip install pandas==1.2.5
