Plotly missing orca

Question

I have small problem when exporting static chart using plotly.

Plotly does not correctly recognize that I have orca installed and I have still error related to missing orca. I try to change the orca directory but it is still not working. Anyone who knows what is wrong?

My code:

import plotly.graph_objects as go
import orca
import plotly

#%%
fig = go.Figure(data=go.Candlestick(x=pricedata.index,
                    open=pricedata['bidopen'],
                    high=pricedata['bidhigh'],
                    low=pricedata['bidlow'],
                    close=pricedata['bidclose']),)
#%%
fig.show()

#%%
plotly.io.orca.config.executable = r'C:\Users\Kuba\AppData\Local\Programs\Python\Python37\Lib\site-packages\orca'
plotly.io.orca.config.save()

#%%

fig.write_image("images/fig1.png")

Here is described how to solve it but it does not work for me:

https://plot.ly/python/orca-management/#configuring-the-executable

The orca version is 1.5.1

Thanks.

If you haven't installed orca yet, you can do so using conda as follows:

    $ conda install -c plotly plotly-orca

Alternatively, see other installation methods in the orca project README at
https://github.com/plotly/orca.

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

Answer 1

try kaleido, it worked for me. It is an alternative to orca

conda install -c plotly python-kaleido

Answer 2

What worked for me on Windows with Pycharm and Python 3.6 is:

• Following https://github.com/plotly/orca#installation - Method 4: Standalone binaries:

  • Download windows-release.zip from https://github.com/plotly/orca/releases
  • Install the executable
  • Right click on the desktop newly created Orca icon to get the path where the application was installed.

• From the plotly\io folder (in my case C:\Users\ventafri\AppData\Local\Programs\Python\Python36\Lib\site-packages\plotly\io ) open _orca.py

Substitute:

 # Try to find an executable
 # -------------------------
 # Search for executable name or path in config.executable
 executable = which(config.executable)
 path = os.environ.get("PATH", os.defpath)
 formatted_path = path.replace(os.pathsep, "\n    ")

with:

# Try to find an executable
# -------------------------
# Search for executable name or path in config.executable
executable = r"C:\Users\ventafri\AppData\Local\Programs\orca\orca.exe"
path = os.environ.get("PATH", os.defpath)
formatted_path = path.replace(os.pathsep, "\n    ")

Answer 3

Susanna's answer is probably much better, but what worked for me is to downgrade to orca 1.2.1:

conda remove plotly plotly-orca
conda install -c plotly plotly-orca==1.2.1

Answer 4

#Try with installing these packages on Colab:

fig.show()
fig.write_image("gdrive/My Drive/destinationfolder/figname.png")

Then generate your figure- not including code here -Save the figure as:

 fig.show() fig.write_image("figname.png")#change format if needed

Or save the generated figure on Google drive as:

 fig.show() fig.write_image("gdrive/My Drive/destinationfolder/figname.png")

Answer 5

From the plotly docs

pip install -U kaleido

Answer 6

I'm also facing the same issue, you can use kaleido to save static image while working with plotly.

https://medium.com/plotly/introducing-kaleido-b03c4b7b1d81

Answer 7

I had a similar issue when trying to generate static images with plotly in jupyter notebook with kernel using other than base conda environment.

I had to install plotly-orca in the base environment as well for it to work.

Answer 8

What worked for me was installing the.exe file from https://github.com/plotly/orca/releases

and then running this with the file path to the newly created.exe file.

import plotly plotly.io.orca.config.executable = '...../orca/orca.exe'

Answer 9

if you are still facing dependencies issues may be install pip install urbansim may resolve it.
