下载nvdiffrast失败

[2741913295]

当我在运行pip install -r requirements.txt时，出现错误`Collecting git+https://github.com/NVlabs/nvdiffrast.git (from -r requirements.txt (line 14)) Cloning https://github.com/NVlabs/nvdiffrast.git to /tmp/pip-req-build-ukf7q7m7 Running command git clone --filter=blob:none --quiet https://github.com/NVlabs/nvdiffrast.git /tmp/pip-req-build-ukf7q7m7 fatal: unable to access 'https://github.com/NVlabs/nvdiffrast.git/': Failed to connect to github.com port 443 after 134752 ms: Couldn't connect to server error: subprocess-exited-with-error
