AttributeError: 'Cycler' object has no attribute 'by_key' when python3 mnist_1.0_softmax.py

[martin-gorner]

Try to upgrade matplotlib:
pip3 install --upgrade matplotlib

[alfonsoeromero]

I had the same problem, but I upgraded matplotlib to the last version via pip and it seems to work.

[martin-gorner]

The reason is that on Linux, you need to install matplotlib with apt-get because that also pulls in the graphics backend on which matplotlib relies.
But unfortunately, the version of martplotlib you get is not the freshest.

after upgrading the matplotlib according to @martin-gorner advice, the problem disappeared:

$ pip3 install --upgrade matplotlib

You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

@martin-gorner I suggest that It is better to put the "matplotlib upgrade" step into INSTALL.txt.

[showforj]

请问这个问题 怎么解决了

[bigwhite]

@showforj I have commented the __get_histogram_cyclecolor invoking in init and do some hard coding to self._color4 and self._color5：

def __init__(self, title1=None, title2=None, title3=None, title4=None, title5=None, title6=None, histogram4colornum=None, histogram5colornum=None, dpi=70):
        #self._color4 = self.__get_histogram_cyclecolor(histogram4colornum)
        #self._color5 = self.__get_histogram_cyclecolor(histogram5colornum)
        self._color4 = '#CFF57F'
        self._color5 = '#E6C54A'

Problem fixed by updating matplotlib as per martin-gorner sugestion. Thanks.
