我想在我可以访问的 gpu 服务器上从源代码安装来自 uber 的 ludwig 。我在那里没有管理员权限。
我使用的步骤记录在 ludwig 的入门步骤中：
git clone https://github.com/uber/ludwig.git
cd ludwig
git checkout db6c90a
virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt
python -m spacy download en
python setup.py install
我只是签出一个自定义分支并更改tensorflow为tensorflow-gpu==1.12.0.requirements.txt
在运行 virtualenv 安装步骤时，我总是遇到这个 TypeError：
TypeError: unsupported operand type(s) for -=: 'Retry' and 'int'
OSError: Command /data/home/jburkard/ludwig/venv/bin/python3 - setuptools pkg_resources pip wheel failed with error code 2
我已经尝试了这个问题中提到的所有步骤。但我既没有使用代理，也没有其他提示帮助。
如果能获得更多关于我可以尝试的建议，那就太好了！
