Cannot install because these package versions have conflicting dependencies.

What is the correct version number please? Below is the error message：

ERROR: Cannot install -r requirements.txt (line 4) and torch==1.9.1 because these package versions have conflicting dependencies.

The conflict is caused by: The user requested torch==1.9.1 torchvision 0.8.2 depends on torch==1.7.1

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Sorry for the inconvenience, currently I am trying to complete the setup.py file and make pypi installation available. The version conflict is due to some legacy issues. I solve it manually by: $ pip install torchvision==0.8.2 --no-deps

很抱歉给您带来不便，目前我正在尝试完成 setup.py 文件并使 pypi 安装可用。 版本冲突是由于一些遗留问题。我通过以下方式手动解决它： $ pip install torchvision==0.8.2 --no-deps Thank you for your reply, the problem has been solved, can I ask you by the way, do you need to send real international mail to apply for the UDIVA dataset? Or just need an email? I have some doubts after looking at the application requirements for this dataset
