Unit test test_v2_api, reader_tests, test_ploter failed on NVIDIA DRIVE PX 2.

When running python unit test, Paddle will deploy its own copy of python, and install all modules needed using pip install. When running those unit tests on NVIDIA DRIVE PX2, it failed to install paddle-0.10.0-py2-none-any.whl and caused those unit tests failed. Detailed information is listed as follows:

On NVIDIA DRIVE PX2, we can use apt-get install python-opencv instead of pip install opencv-python to install opencv.

Cannot install paddle‘s python package because of the same problem.
