我想卸载pandas 只,而不是有别的降级.
据我所知,这些包都依赖 …
我想运行 SfePy 演示,但使用 Mayavi 显示时出现问题。请参阅http://sfepy.org/doc-devel/installation.html#requirements
我有:
conda create --name SfePy36 python=3.6安装 mayavi 使用 conda install -c conda-forge mayavi
安装 pip3 使用python3 get-pip.py(从这里)
安装 PyQt5 使用 pip3 install PyQt5
我不知道如何独立检查 PyQt5 是否安装正确。如果我重复,pip3 install PyQt5它会告诉我它已经安装,但这并不意味着它已正确完成或位于正确的位置。
当我运行下面非常简单的 mayavi 测试时,出现以下错误。
