I tried that image in order to resolve some other issues. However, after I made some more installings on the image and run a simple test case with nose, I got the following error:

Traceback (most recent call last): File "/usr/local/lib/python3.5/site-packages/nose/case.py", line 198, in runTest self.test(*self.arg) File "/selenium/test1.py", line 42, in test_fac driver, wait, selector = init() ValueError: too many values to unpack (expected 3)
