在安裝requirements.txt報錯，裡面有git，如：

transformers @ git+http://github.com/ibeltagy/transformers.git@longformer_encoder_decoder#egg=transformers

解決

1.新開一個cmd，輸入

git config http.sslVerify "false"

2.使用pip命令安裝

pip install git+https://github.com/ibeltagy/transformers.git@longformer_encoder_decoder#egg=transformers
