Orca CLI doesn't work with Python subprocess.Popen

[PlotlyUser2]

Well, I've just tried to create an image by using orca within the python api. However this code doesn't produce any image:

import subprocess

json_res = json.dumps({"data": [{"y": [1,2,1]}]})
command = f"orca graph {json_res} -o fig.png" 
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=None, shell=True)

#Launch the shell command:
output = process.communicate()

print (output[0])

It returns: done with code 1 in 2.59 ms - failed or incomplete task(s)

Thanks for the report. Nothing appears suspicious.

I ran

from subprocess import call
import json

fig = {"data": [{"y": [1,2,1]}]}
call(['orca', 'graph', json.dumps(fig)])

as in the README instructions again in Python3.5 and things work fine.

Maybe someone more familiar with python's subprocesses could help us out?

@etpinard When I try to run your code piece, I get the FileNotFoundError: [WinError 2] error. But when I run this:

from subprocess import call
import json

fig = {"data": [{"y": [1,2,1]}]}
call(['orca', 'graph', json.dumps(fig)], shell=True)

Out[2]: 0

Well, then I get 0.

[etpinard]

Well, then I get 0.

If that 0 means exit code 0, then the export should have succeeded.

[PlotlyUser2]

Where does the image file should be created?

[etpinard]

in the same directory as where you're running your script.

[PlotlyUser2]

Yup, your code works. Thanks!

But still the above code fails.

I can confirm the above too. Not using the shell argument works, and file will save to the expected output.
