python - 即使 conda 说已安装，Numpy 也无法导入

Question

Numpy 不知何故停止工作。我认为这可能是因为我更改了我的 $PATH 环境变量，但这并没有什么意义。我确实运行了 source，然后是 source .bashr 然后是 source .bashrc 然后是 source ~/.bashrc all连续，所以这可能与它有关。

conda list | grep numpy

仍然返回合理的东西

这是我尝试导入 numpy 时打印的错误

>>>import numpy as np

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'numpy'
Error in sys.excepthook:
Traceback (most recent call last):

import apt
File "/usr/lib/python3/dist-packages/apt/__init__.py", line 23, in <module>
import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

Original exception was:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'numpy'

编辑:

我已经尝试导入我通过 Conda 安装的所有其他包，但它们都没有工作。他们似乎都给出了类似的错误(1. sys.excepthook 中的错误: 和 2. No module named 'apt_pkg')

大图:

1) Uninstall conda first
2) Again install conda
3) Then install Anaconda from its official documentation.

复制这些命令:

conda install anaconda-clean
anaconda-clean --yes
rm -rf anaconda3/                 # uninstall

cd /tmp                           # install
curl -O https://repo.continuum.io/archive/Anaconda3-5.0.1-Linux-x86_64.sh
sha256sum Anaconda3-5.0.1-Linux-x86_64.sh
# verify legit shell file ^
bash Anaconda3-5.0.1-Linux-x86_64.sh
   # hit 'enter'
yes
source ~/.bashrc
conda install -c anaconda numpy   # install packages
conda install -c anaconda tensorflow
