orca executable not found

[FromTravis]

Good morning all,

I keep bumping the error below when trying to make Orca work. Although when using the line: !orca graph “{ “data”: [{“y”: [1,2,60]}] }” -o fig.png on a command window it works.

and second question: to save an image cam you just create the figure and then fig.write_image("images/fig1.png") like in the plotly website ? I m asking because i see posts of people writing about launching the orca server etc.. but i don't really see full codes on how to do so.

After installation is complete, no further configuration should be needed. If you have installed orca, then for some reason plotly.py was unable to locate it. In this case, set the `plotly.io.orca.config.executable` property to the full path of your orca executable. For example: >>> plotly.io.orca.config.executable = '/path/to/orca' After updating this executable property, try the export operation again. If it is successful then you may want to save this configuration so that it will be applied automatically in future sessions. You can do this as follows: >>> plotly.io.orca.config.save() If you're still having trouble, feel free to ask for help on the forums at https://community.plot.ly/c/api/python

I 've navigated around the issue by not using write image method and instead call(['orca', 'graph', json.dumps(fig, cls=plotly.utils.PlotlyJSONEncoder), '-o', 'fig1b','-d','images','-f','svg'])

A pity but it does the job!

In the terminal $ which orca '/-/anaconda3/bin/orca' ('/path/to/orca')

plotly.io.orca.config.executable = '/-/anaconda3/bin/orca' plotly.io.orca.config.save()
