ImportError: No module named PyQt4.QtCore

Question

I\'ve reïnstalled my ssh server, so I also need to reïnstall my Python packages.

I did that, but I still get the error:

ImportError: No module named PyQt         


        

Answer 1

I got the same error, when I was trying to import matplotlib.pyplot

In [1]: import matplotlib.pyplot as plt
...
...
ImportError: No module named PyQt4.QtCore

But in my case the problem was due to a missing linux library libGL.so.1

OS : Cent OS 64 bit

Python version : 3.5.2

$> locate libGL.so.1

If this command returns a value, your problem could be different, so please ignore my answer. If it does not return any value and your environment is same as mine, below steps would fix your problem.

$> yum install mesa-libGL.x86_64

This installs the necessary OpenGL libraries for 64 bit Cent OS.

$> locate libGL.so.1
/usr/lib/libGL.so.1

Now go back to iPython and try to import

In [1]: import matplotlib.pyplot as plt

This time it imported successfully.
