Failure to save image offline due to dataframe size - FileNotFoundError: [WinError 206] The filename or extension is too long

[travis1]

If you create a dataframe of random numbers with say 1000 lines.

df = pd.DataFrame(np.random.randint(0,1000,size=(1000, 9)), columns=list(‘ABCDEFGHI’))

and you then want to save a scatter graph like this:

import plotly.express as px
fig1 = px.scatter(df, x=“A”, y=“B”, size=“D”, color=“E”,
hover_name=“F”, )

fig1.update_layout(title=‘test’,width=1200,height=500)
fig1.show()

and you then want to save that image
call([‘orca’, ‘graph’, json.dumps(fig1, cls=plotly.utils.PlotlyJSONEncoder), ‘-o’, ‘graph_name’,’-d’,‘images’,’-f’,‘svg’])

you get this error message below. if i reduce the size of the dataframe to 800 lines then it works.
any idea how to remove this size cap ?

Hi @travis1 it seems that you’ve had this problem several times in the past. Would you mind linking here to previous relevant posts you made so that we can address the issue with all possible information? Thanks!

[travis1]

bonjour Emmanuelle, merci pour votre réponse.

sorry, what do you mean by linking ? to place the link to my other posts ?

well there two things I ve noticed.

to make save image functionality work is quite hard and I don’t know why. some co worker of mine had the same issue. that’s why I use the orca call instead.
here are my other post on this issue1

Save image offline error: unable to communicate with the local orca server process

hi all, I m using Plotly successfully and save image via the subprocess call orca method which works from subprocess import call import json import plotly fig = {“data”: [{“y”: [1,2,1]}]} call([‘orca’, ‘graph’, json.dumps(fig, cls=plotly.utils.PlotlyJSONEncoder)]) but when I use the function: fig.write_image(“images/fig1.png”) I always get this error : ValueError: For some reason plotly.py was unable to communicate with the local orca server process, even though the server process seems …

issue 2 :
the size of the resulting image ( or the amount of information in it) seems to cause an issue with “this file name too long” . but I can’t quite figure out where in the library this is happening.

Call Orca error: FileNotFoundError: [WinError 206] The filename or extension is too long

hi, i can’t use the write_image function ( never managed to make it work. Here the post i put up there but nobody seems to know the answer. Save image offline) but for some strange reasons, i can still save images using the call orca function in my python script. From time to time though, it blocks on some name of file too long wich is not the case call([‘orca’, ‘graph’, json.dumps(fig1, cls=plotly.utils.PlotlyJSONEncoder), ‘-o’, ‘the_image_name’,’-d’,‘images’,’-f’,‘svg’]) File “C:\Program…

would be amazing to know . the library is fantastic.

I would be very happy to help the Plotly project with my ( very modest ) skills.

thanks!

I ve just tried again on a Mac ( the above is on windows).
I find the same issue but the limit is at 9500 lines on the random dataframe

---

import plotly.express as px
import pandas as pd

df = pd.DataFrame(np.random.randint(0,1000,size=(10000, 9)), columns=list(‘ABCDEFGHI’))
df.head()
fig1 = px.scatter(df, x=“A”, y=“B”, size=“D”, color=“E”,
hover_name=“F”, )

fig1.update_layout(title=‘test’,width=1200,height=500)
fig1.show()

1000 lines of dataframe gives this error on Mac ( kind of similar but wording is different)

call([‘orca’, ‘graph’, json.dumps(fig1, cls=plotly.utils.PlotlyJSONEncoder), ‘-o’, ‘graph_name’,’-d’,‘images’,’-f’,‘svg’])

Anyone faced the same error of not being able to save a figure to the size of the image ?

thanks

Hi All,

Anyone ever had the issue to not be able to save an image because it’s deemed too large ?
