Полностью отсутствует косатка

У меня небольшая проблема при экспорте статической диаграммы с использованием plotly.

Plotly неправильно распознает, что у меня установлена ​​orca, и у меня все еще есть ошибка, связанная с отсутствующей orca. Я пытаюсь изменить каталог orca, но он все еще не работает. Кто-нибудь, кто знает, что не так?

Мой код: 

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")

Здесь описано, как ее решить, но у меня это не работает:

Версия orca - 1.5.1

Спасибо.

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()
