I am using a Python3 installation in a Ubuntu distribution in WSL2 on a Windows 10 machine.
Over the last two months, i did not code that much. Now i started again and faced the following issue:
The following code hangs for ~2min:
import matplotlib.pyplot
After 2 min, i got the following output:
Traceback (most recent call last):

ImportError: Failed to import any qt binding
The issue has already been described here: import matplotlib.pyplot hangs
But the suggested solutions did not work.
I then ran
sudo pip install --upgrade matplotlib
which helped, as the import command works now, but it still takes 2 min to execute!
Do you know, why this command takes so much time?
Uninstalling and reinstalling Matlplotlib did not help.
Uninstalling and reinstalling python 3.X did not help.
What did work was resetting the Ubuntu installation in the windows settings, e.g. see here:

I assumed the issue was with the scipy because all the following errors come from that module. I checked and I have everything installed properly for the scipy module.
Please help! Thank you!
Run any command prompt you are using as administrator and then run pip install lib_name --force-reinstall
Try using these two commands they will help you:
conda remove --force scipy
And:
pip install scipy
Hello I had the same issue than you. Depend on wich version of python you use you should choose a version thinkx. I recommend you to go on the website of thinkx and check out for past udapte. In my case that was with matplotlib 3.3.1 for python 3.7. I went in git bash and used
pip install matplotlib==3.0.1
and everything worked. I had the same issue with seaborn and it worked.
I'm trying to use mayavi in python to visualize a pointcloud, and cannot resolve this error. I'm sure it is an easy pip install, but I am unsure of the command. Any help is much appreciated! Thanks!
BTW, I am running Ubuntu 18.04 and have tried installing scipy as mentioned here: Python import error "getfullargspec". I have also ran pip install traitsui. Additionally, I have rebooted my system.
Update:
After further digging, it appears that it may be an issue with Python versions. I was able to get it to run with Python3, but not Python 2.7 (I need it to work with python 2). I have also tried modifying the code within handler.py to getargspec instead of getfullargspec. I was given an error about trait_factory by doing this
Here is the entire printout:

The solution for this problem was to use older packages. Not all of the dependencies such as traitsui are compatible with Python 2.7. Even though an older version of mayavi was installed, the dependencies that are installed automatically are not compatible (they only support Python 3).
Here are the versions that work well together for me:
mayavi==4.6.2
traitsui==6.1.3
traits==5.2.0
numpy==1.17.4
pyface==6.1.2
To install a specific version, just run sudo pip install packageName==#.#.#
Tried anaconda today , it seems fine but when I tried to launch Spyder each time I get this error: Traceback (most recent call last):

Any help regarding this ? Also how do I get python 3.6.3 in anaconda..?
The problem is you have two Python versions installed in your system: one in C:\ProgramData\Anaconda3\ and the other in C:\Users\Jaker\AppData\Roaming\Python\Python36.
Please uninstall one of them and the problem will be solved.

Importing scipy.stats gives the error above. I recently installed Python anaconda. I have tried reinstalling numpy and scipy but to no avail. I am using Ubuntu 14.04
The command "which -a python" gives the following lines as output :-
/home/abhishek/anaconda/bin/python
/usr/bin/python
You should unset PYTHONPATH. It is causing your Anaconda Python to pick up packages installed in /usr/local instead of just the Anaconda packages (which should work correctly).
It was pointed out to me that the scipy installation in /usr/local/ was broken and that I needed to uninstall it.
sudo pip uninstall scipy
This fixed the problem.
The problem is likely a configuration issue, because getting the installation correct on Macs seems to be tricky. I'm running Mavericks and matplotlib 1.4.x, yet when I open a Python 2.7.5 shell and import pylib, I get this error:
>>> import pylab

I have libpng16 installed, but not libpng15.
I saw a hardcoded reference to libpng15 in _png.so.
Uninstall and install of matplotlib fixed the issue for me.
You can always moke it by generating a soft link like this
sudo ln -s /opt/X11/lib/libpng.dylib /usr/local/lib/libpng15.15.dylib
Not the cleaner solution but I haven't figure out why matplotlib stubbornly asks specifically for libpng15 and not any 15 or greater.
