[FIXED] ImportError: Failed to import any qt binding, Python - Tensorflow

Issue

I'm starting my adventure with Tensorflow. I think I installed everything correctly, but when running this code, PyCharm returns an error:

My code which I am trying to run:

for k in range(num_iter):

plt.xticks([0.0, 0.5, 1.0]); plt.yticks([0.0, 0.5, 1.0])
plt.show()

I think it follows another version of python. How can I run the code without error. I installed qt-binding and added tensorflow to my PyCharm.

Any help will be appreciated.

Solution

It solved my problem.

pip uninstall matplotlib
python -m pip install --upgrade pip
pip install matplotlib
