Pip suddenly not working on Jetson Nano 2GB

[grasschan1010]

As the title said, Python-pip suddenly not working. All the frameworks installed by pip are lost. I searched all forums but I could not find the solution.
Here is Traceback when I run command pip3 list:

Traceback (most recent call last):
  File "/usr/local/bin/pip3", line 7, in <module>
    from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip._internal'

I have tried to reinstall pip but the problem still persists
Please help me fix this problem. Thanks in advanced.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Hi,

How do you reinstall the tool?
Could you give the below command a try?

$ sudo apt install --fix-missing python3-pip

Thanks.
