pw can't display plotnine and breaks plotnine.ggplot as a side-effect #56
Description
In the issue that I'm encountering, two things go wrong:
pw.load_ggplot()called on a ggplot object produces the following:
AttributeError: 'ggplot' object has no attribute '_create_figure'
- If, after attempting this, a different cell is run to display a ggplot object, the same error appears. However, ggplot objects have no problem being displayed before attempting to run
pw.load_ggplot().
So it seems that the problem is a side-effect of the functionpw.load_ggplot.
Code blocks to reproduce problem
from plotnine import ggplot, aes, geom_point, scale_color_gradient
from plotnine.data import mpg
p = ggplot(aes(x="displ", y="cty"), mpg)
P = p + geom_point()
P
This displays the plot as expected.
import patchworklib as pw
No problems at import.
pw_P = pw.load_ggplot(P, figsize=(1,1))
This gives the aforementioned attribute error, with the following traceback:
----> 1 pw.load_ggplot(P, figsize=(1,1))

36 # setup
---> 37 figure, axs = self._create_figure()
38 self._setup_parameters()
39 self.theme.setup()
AttributeError: 'ggplot' object has no attribute '_create_figure'
After this, plotnine.ggplot objects start producing the same error. E.g., the following cell produces the same error
P
New ggplot objects suffer the same fate, eg.:
q = ggplot(aes(x="displ", y="cty"), mpg)
Q = q + geom_point()
Q
--> [...] AttributeError: 'ggplot' object has no attribute '_create_figure'
This was tested on a jupyterhub server. The problem only goes away if I restart the jupyterhub kernel.

Apologies for the inconvenience. However, I am unable to continue supporting plotnine in patchworklib due to limited capacity in my labour. I believe patchworklib remains a valuable library even if it only supports matplotlib and seaborn.
If there are many requests like yours, I will consider addressing this issue, but please do not have large expectations..
I'm terribly sorry about this thing...

Patchworklib tentatively supports the newest version of plotnine. However, it likely still contains many bugs and may produce unexpected results. If you find anything, please let me know.

I have the same issue in load_ggplot(ggplot, figsize) when running the script even w/o Patchworklib. It is also solved by a previous version of plotnine.

for anyone who stumbled upon this issue like I did - greatly inspired by patchworklib - plotnine >0.15 supports | / "natively"

thank you @behinger
