我在一个没有root访问权限的系统上的远程Jupyter笔记本上工作，甚至没有一个可以进行许多调整的shell。我可以从 Conda 的存档中检索包并在安装这样的包的笔记本单元中运行函数
!conda install /path/to/package-vvv.tar.bz2
我遇到了我猜错版本号的情况，安装了不兼容的东西。错误消息就像我在下面生成的错误消息，numpy 或 mkl 中的二进制不兼容。
现在，我在拥有管理员访问权限的 Ubuntu 20.10 笔记本上重新跟踪问题。我有一个可重现的问题要展示和分享。
- 使用相同版本的 python、numpy 和 pandas 创建一个环境，就像我们在远程机器上一样：
$ conda create -n cenv-py368 python=3.6.8 pandas=1.1.2 numpy=1.15.4
Solving environment: done
==> WARNING: A newer version of conda exists. <==
current version: 4.5.12
latest version: 4.9.2
Please update conda by running
$ conda update -n base -c defaults conda
## Package Plan ##
environment location: /home/pauljohn/LinuxDownloads/miniconda3/envs/cenv-py368
added / updated specs:
- numpy=1.15.4
- pandas=1.1.2
- python=3.6.8

你同意我发现了一个错误吗？
似乎 Conda 应该可以工作，或者应该说没有兼容的 fastparquet 版本。
