Cannot import matplotlib.pylab in web2py environment (python3) #2010

Open leohaim opened 6 years ago

Describe the bug When I change your welcome example such that I add "import matplotlib.pylab" as first line of the control file "default.py"

I am getting the error: 127.0.0.1.2018-09-14.00-34-40.fce2605f-9ede-4fc8-85dd-b8e2faf76389 <class 'AttributeError'> 'NoneType' object has no attribute 'strip'

If I am importing matplotlib only: import matplotlib it works, but of cours I cannot create plots.

I am using the latest Anaconda distribution (python 3.6.6, matplotlib 2.2.3) on CentOS 6. I am using the latest web2py Version 2.17.1-stable+timestamp.2018.08.06.01.02.56

The detailed output is attached

It may be matplotlib issue. Does "import matplotlib.pylab" work inside python command line?
Also you may get better error message if you run latest web2py code from master branch.

Indeed. It went away when I upgraded to python 3.7 and Matplotlib 3.0.2 For me the issue is now closed.
