python - 尝试 conda 安装 tensorflow 1.4.1 时发生奇怪的 `glibc==2.17` 冲突

Question

我正在尝试使用以下命令使用 tensorflow (GPU) 版本 1.4.1 创建一个新的 conda 环境 conda create -n parsim_1.4.1 python=3 tensorflow-gpu=1.4.1.

但是，它打印出一个奇怪的冲突:

$ conda create -n parsim_1.4.1 python=3 tensorflow-gpu=1.4.1

我的操作系统是CentOS7，

$ uname -a
Linux cpu-s-master 3.10.0-1160.42.2.el7.x86_64 #1 SMP Tue Sep 7 14:49:57 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

这是怎么回事？我该如何解决？

编辑

感谢@merv 的评论，我尝试使用 Mamba，确实它提供了更好的错误消息(而且速度更快)。如果有人感兴趣，那就是成功安装我所需版本的命令:

mamba create -n parsim python=3 "tensorflow-gpu=1.4" pillow opencv -c shuangnan -c anaconda

Conda的报错isn't always helpful . Mamba 有时更好，在这种特殊情况下，它提供:

Encountered problems while solving:
  - nothing provides cudatoolkit 8.0.* needed by tensorflow-gpu-base-1.4.1-py27h01caf0a_0

即使在这里，构建字符串中的 py27 也很奇怪，但它至少将我们定向到 cudatoolkit 8.0，它不再托管在 ma​​in channel 。相反，您需要 include the free channel .以下对我有用:
