Trouble with importing matplotlib

Question

I have a trouble while importing matplotlib in PyCharm4.5.3

from pylab import *`

Error:

Traceback (most recent call last):
  File "/home/vera/PycharmProjects/COM/backend/17.08", line 10, in <module>

    from pylab import *

  File "/usr/lib/python3/dist-packages/pylab.py", line 1, in <module>

from matplotlib.pylab import *

  File "/usr/lib/python3/dist-packages/matplotlib/pylab.py", line 226, in <module>

import matplotlib.finance

  File "/usr/lib/python3/dist-packages/matplotlib/finance.py", line 21, in <module>

from matplotlib.dates import date2num

  File "/usr/lib/python3/dist-packages/matplotlib/dates.py", line 119, in <module>


     from dateutil.rrule import (rrule, MO, TU, WE, TH, FR, SA, SU, YEARLY,
      File "/usr/lib/python3/dist-packages/dateutil/rrule.py", line 55
        raise ValueError, "Can't create weekday with n == 0"
                    ^
SyntaxError: invalid syntax

Process finished with exit code 1

It was working before I installed PyCharm Community Edition. In professional edition it worked. But after installation the programm broked even in PyCharm professional Edition.

What i did wrong?

I also had the same problem while using matplotlib in anaconda virtual environment. Updating the dateutil lib to the latest version worked for me :

pip install python-dateutil --upgrade

Hope this helps.

The file rrule.py from the dateutil module uses old (invalid) syntax to raise an exception.

Maybe you installed an old version of dateutil?

Check if you have dateutil version <= 1.5.x installed. If yes, then you should install a >= 2.x version.

I had the same problem and solved it reinstalling the python-dateutil library:

pip3 uninstall python-dateutil
pip3 install python-dateutil
