ModuleNotFoundError: No module named 'PyQt4'

I cloned the project onto my local machine and then ran the Jupyter notebook, and hit the error,
raise ImportError("Failed to import any qt binding"), Matplotlib/backends/qt_compat.py:165
when executing %matplotlib qt
Is this because of my environment, or something else?

Hello,

The test_image.jpg you provided in the calibration_wide/ does not match the figure in Udacity's ND0013 Exercise 1.2.1: Correcting-for-Distortion.ipynb.

This affects the test data provided to us in the wide_dist_pickle.p pickle file to compare the student's object points/image points returned from the OpenCV findChessboardCorners() method as well as the camera intrinsics/extrinsic from OpenCV's calibrateCamera().

Because of this, students are unable to compare their solution to factual test data using their version of test_image.png given in the exercise workspace.

Please update either this test_image.jpg file and the corresponding data in the pickle file, or provide Udacity students in their Jupyter workspace the actual test_image.png shown in the assignment figure below:

More information

• This is an ongoing issue discussed with the Mentor (Neha) on Udacity Knowledge forum here
• The "Original Image" shown in the figure below appears to be GOPR0038.jpg
• However, using this as the "test_image" and checking my solution with Udacity's test() against the pickle file, I receive a 'Oops! that looks different than my result!' error.
• Using the current test_image.jpg, this is what I obtain after correction:
  
  which is clearly a very different result than the expected above.
