pip3 falhando com o ImportError

Question

Eu usei o Python v3.5 para codificar com o pacote tensorflow . Agora eu tentei atualizar para a versão mais recente e pip3 caiu o tempo todo com erro seguinte quando eu apenas executar pip3 :

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pip/_vendor/__init__.py", line 33, in vendored
    __import__(vendored_name, globals(), locals(), level=0)
ImportError: No module named 'pip._vendor.pkg_resources'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/pip3", line 9, in <module>
    from pip import main

Estou usando um Ubuntu 16.10 atualizado e não estou ciente de nenhuma alteração de software que possa estar relacionada a esse problema.

FYI: pip , a versão do Python v2.7, funciona sem problemas.

    

Answer 1

Parece que algo quebrou os pacotes do Pip3. Você pode reinstalá-lo com:

sudo apt install --reinstall python3-pip

    

Answer 2

Tente atualizar seu pip3 digitando pip3 install --upgrade pip no seu terminal.

EDIT: alterado pip para pip3
