DVC|权限被拒绝错误:无法再现阶段:无法运行:.py，已退出，返回126

Question

目标：通过运行.py文件。CCD_ 2。

在dvc.yaml中，它之前有一些阶段不会产生错误。

dvc exp run:

(venv) me@ubuntu-pcs:~/PycharmProjects/project$ dvc exp run

解决方案1

.py文件未作为脚本运行。

他们需要；如果要在dvc.yaml中的每个stage运行一个.py文件。

为此，您需要在每个.py文件的底部附加锅炉板代码。

if __name__ == "__main__":
# invoke primary function() in .py file, w/ params

解决方案2

chmod 777 ....py

Soution 3

我忘记了cmd:中的python

load_data:
cmd: python pdl1_lung_model/load_data.py
