4 years ago @karlkrach could you please try importing matplotlib & seaborn in a python interpreter and check if it throws the same error?

4 years ago i already did, see "additional context": if i start python from command line, i can run "import seaborn" and "import matplotlib" without problem. or did i misunderstand you? also: thanks for getting back to me!

4 years ago @karlkrach sorry I didn't notice that in your issue description.
So here's where the error is happening.
try:
import matplotlib as mpl
if platform == "darwin": # OS X
mpl.use('TkAgg')
import matplotlib.patches as patches
import matplotlib.path as path
import matplotlib.patheffects as PathEffects
import matplotlib.pyplot as plt
import seaborn as sns
from matplotlib import ticker
from matplotlib.lines import Line2D
from mpl_toolkits.mplot3d import Axes3D
except ImportError:
logger.error(
' matplotlib or seaborn are not installed. '
'In order to install all visualization dependencies run '
'pip install ludwig[viz]'
)
sys.exit(-1)Could you please help me narrow down the error by running those import commands?
I think it's because of mpl_toolkits, but I want to make sure. We might need to add another if platform == 'darwing' before the mpl_toolkits import.
Thanks

4 years ago if i paste this in a script 1:1 and run, i get:
portabel:ludwig user$ python matplottest.py
Traceback (most recent call last):
File "matplottest.py", line 4, in <module>
if platform == "darwin": # OS X
NameError: name 'platform' is not definedif run the same but with lines 4 & 5 (if…) commented out, it does not throw any error.

4 years ago oops. you need to do from sys import platform first.

4 years ago This is weird, you are using Mac OS, so you should have TkAgg as a backend. That's the whole reason why there's that check if platform == 'darwin'.
Could you please both tell us what is the value of the platform variable and try to replace TkAgg with agg as suggested here?

4 years ago Reproduced this exact issue. My platform variable is darwin
As suggested: mpl.use('agg') ran without issue.
Got same error when I updated examples/titanic/multiple_model_training.py (as referenced in matplotlib#9017):
import matplotlib as mpl
mpl.use('agg')Other suggestions?

4 years ago @seekayel Thank you for reporting on this. Could you please tell us what's your version of MacOS and your version of Python and matplotlib? Asking because we introduced that if with TKAgg specifically for mac users because it was solving the problem they were encountering with matplotlib, while now it looks like that is the source of the problem, so I suspect it may have to do with different versions of MacOS shippint with different bundles of python.

I am using pyenv to install my pythons and pipenv w/ Pipfile to manage dependencies and virtualenv creation.
MacOSX: 10.15.6 Python: 3.7.7 via pyenv matplotlib: 3.3.0 via pipenv
import matplotlib as mpl
import sys
print(f"sys.platform: {sys.platform}")
print(f"sys.version_info: {sys.version_info}")
print(f"mpl.__version__: {mpl.__version__}")
print(f"mpl.rcsetup.non_interactive_bk: {mpl.rcsetup.non_interactive_bk}")
print(f"mpl.rcsetup.interactive_bk: {mpl.rcsetup.interactive_bk}")Output:
sys.platform: darwin
sys.version_info: sys.version_info(major=3, minor=7, micro=7, releaselevel='final', serial=0)
mpl.__version__: 3.3.0
mpl.rcsetup.non_interactive_bk: ['agg', 'cairo', 'pdf', 'pgf', 'ps', 'svg', 'template']
mpl.rcsetup.interactive_bk: ['GTK3Agg', 'GTK3Cairo', 'MacOSX', 'nbAgg', 'Qt4Agg', 'Qt4Cairo', 'Qt5Agg', 'Qt5Cairo', 'TkAgg', 'TkCairo', 'WebAgg', 'WX', 'WXAgg', 'WXCairo']Anything other info you need?

4 years ago I tried to replicate the issue, but was not able to. Could you please try a couple things to see if they solve your issue? In that case i would at least have narrowed down the issue.
Can you please do clean install of ludwig with a new virtual environment using virtualenv instead of pyenv and pipenv? Here my suspicion is that there are some differences in the way those tools install matplotlib that have the effect of not providing you with TKAgg.
If that doesn't work, can you try replacing the backend with MacOSX? If that works I can add in the code several attempts, to load tkagg, then macosx and finaly agg and raise the error only if non of them loads.
Thank you for your patience.
Describe the bug Although
pip install ludwig[viz]was sucessful, any call of ludwig visualize results in the messagematplotlib or seaborn are not installed. In order to install all visualization dependencies run pip install ludwig[viz]To Reproduce Steps to reproduce the behavior:
Expected behavior Should render graphs and not return an error.
Environment (please complete the following information):
Additional context If I start Python from CLI, I can import matplotlib and seaborn with no problem. Apart, see shell output below:
