我可以通过pip安装tensorflowgpu，但由于依赖性问题我不能在conda中安装？

Question

我以前安装了tensorflow，但我也想要GPU版本。我不明白为什么我不能在conda中安装tensorflow gpu，但我可以在pip中安装？我在使用conda安装时遇到了很多依赖性问题：

(base) cs_u@dual2080:~/Desktop/foo$ conda install tensorflow-gpu
WARNING conda.base.context:use_only_tar_bz2(632): Conda is constrained to only using the old .tar.bz2 file format because you have conda-build installed, and it is <3.18.3.  Update or remove conda-build to get smaller downloads and faster extractions.

不过，皮普很好：

如果有人可以通过安装pipi来解决问题，那么是否可以通过安装pipi来解决？在
