The workaround of androst (4 Jan 2017) did not work for me. However, I found out that the lines of code which androst cited from generic_utils.py were never executed when I ran my code, because the condition in the embracing "if-clause" was always False. When I out-commented the if-clause, and set the corresponding variable (manually) to "True", it worked.

This is what I changed (for me: lines 311-314 of generic_utils.py):

    #self._dynamic_display = ((hasattr(sys.stdout, 'isatty') and
    #                          sys.stdout.isatty()) or
    #                         'ipykernel' in sys.modules)
    self._dynamic_display = True   # inserted to overwrite the above (workaround by KS)

Then the progress bar worked nicely :-)
