Internal AttributeError: Unknown property facecolor

Dear nilearn-Team,

I am using your package some months now. Somehow I wasn't able to plot Nifti1 images anymore. Using and function from nilearn.plotting gives me the AttrributeError: Unknown property facecolor.

Here is the Traceback:

`Traceback (most recent call last):

  File "<ipython-input-4-01b0b33a2aaf>", line 4, in <module>
    threshold= stcdata.min(), annotate=True, title='iter _ t=%.2f ms' % (t_in_ms), cmap='n_jet')

  File "/home/daniel/anaconda2/lib/python2.7/site-packages/matplotlib/artist.py", line 856, in update
    raise AttributeError('Unknown property %s' % k)

AttributeError: Unknown property facecolor`

I am hoping you can tell me how to fix this, because I am using your tools very often.

Thanks in advance and greetings, Daniel

    Did you update matplotlib recently? What version are you using?

    Along with the version of matplotlib as Gael asked. Could you please also give us some script to reproduce the error ? It would make us easy to see what is going on. Thanks for the minimal reproducible script.

    I did "update" matplotlib recently. I am using matplotlib 2.0.2 now. I already solved the problem myself. But somehow another, different Error pops up.

    Just by trying to import nilearn.plotting the Traceback looks like this

    from nilearn import plotting
    Traceback (most recent call last):
      File "<ipython-input-18-35cd2f5e057b>", line 1, in <module>
        from nilearn import plotting
      File "/home/daniel/anaconda2/lib/python2.7/site-packages/nilearn/plotting/__init__.py", line 38, in <module>
        from . import cm
      File "/home/daniel/anaconda2/lib/python2.7/site-packages/nilearn/plotting/cm.py", line 144, in <module>
        _cmaps_data['ocean_hot'] =  _concat_cmap(_cm.ocean, _cm.hot_r)
      File "/home/daniel/anaconda2/lib/python2.7/site-packages/nilearn/plotting/cm.py", line 70, in _concat_cmap
        colors = cmap1(ps)
      File "/home/daniel/anaconda2/lib/python2.7/site-packages/matplotlib/colors.py", line 487, in __call__
        cbook._putmask(xa, xa == 1.0, almost_one)
    AttributeError: 'module' object has no attribute '_putmask'

    Unfortunately the minimal reproducible script only contains one line: from nilearn import plotting

    Thanks for your assistance, Daniel

    I don't want to reinstall nilearn, but I will give it a try. Furthermore, I remind you that the problem is not importing nilearn.plotting, but that there is something wrong with a module.

    Solved the problem. Since the problem was a false/defect module I went for: 1. Uninstall matplotlib 2. Uninstall nilearn and then installed all again. There really was a dependecy issue with nilearn and matplotlib.

    Nevertheless, I thank you for your help.

    Just curious, which matplotlib version have you updated ?

    Can you close this issue if everything seems OK ?

    Everything seems okay. I am using matplotlib version 2.1.0.
