File "/usr/bin/pip", line 9, in from pip import main ImportError: cannot import name m

1、

在终端用sudo pip install xxx时报错

ubuntu@ubuntu-ST-KN:~/caffe/python$ for req in $(cat requirements.txt); do sudo pip install $req; done
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
ImportError: cannot import name main
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
ImportError: cannot import name main

解决方法：

https://blog.csdn.net/weixin_40208575/article/details/81392076

ubuntu@ubuntu-ST-KN:~/caffe/python$ sudo gedit /usr/bin/pip

讲

from pip import main
if __name__ == '__main__':
    sys.exit(main())

改为;

from pip import __main__
if __name__ == '__main__':
    sys.exit(__main__._main())
    #注意仔细看清楚是两个_还是一个_

再接着执行：

ubuntu@ubuntu-ST-KN:~/caffe/python$ for req in $(cat requirements.txt); do sudo pip install $req; done

2、

>>> import caffe
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/ubuntu/caffe/python/caffe/__init__.py", line 1, in <module>
    from .pycaffe import Net, SGDSolver, NesterovSolver, AdaGradSolver, RMSPropSolver, AdaDeltaSolver, AdamSolver, NCCL, Timer
  File "/home/ubuntu/caffe/python/caffe/pycaffe.py", line 15, in <module>
    import caffe.io

  File "/home/ubuntu/caffe/python/caffe/proto/caffe_pb2.py", line 6, in <module>
    from google.protobuf.internal import enum_type_wrapper
ImportError: No module named google.protobuf.internal

解决;

sudo apt-get install python-protobuf
