pip3: command not found

locate pip3

Terminal should give you a list of results like this

//pip3
//pip3.x

make a symbolic link to where your pip3 is located

ln -s //pip3.x /usr/local/bin/pip3

 

如果执行pip install keras命令出现

Traceback(most recent call last):

     File "/usr/local/bin/pip" , line 7 ,in

       from pip._internal import main

ImportError: No module named _internal

可以尝试 ： python -m pip install --upgrade pip 命令解决
