#### 出現下列錯誤

####ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

####We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

#### 不用擔心

確認 https://mmocr.readthedocs.io/en/dev-1.x/get_started/install.html 底部的版本資訊
