Попытка сохранить рисунок на сервере (работает на настольном ПК) через SSH.

Я подключаюсь к ssh-Y (потому что сначала он выдал несколько ошибок X11) и запускаю рабочий скрипт. Получите эту ошибку в последней строке (write_img):

 Traceback (most recent call last):

ValueError:
The orca executable is required in order to export figures as static images,
but the executable that was found at '/home/astro/mpisketzis/anaconda3/bin/orca'
does not seem to be a valid plotly orca executable. Please refer to the end of
this message for details on what went wrong.

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

Here is the error that was returned by the command
    $ /home/astro/mpisketzis/anaconda3/bin/orca --help

[Return code: 127]

Из этой строки,

 /home/astro/mpisketzis/anaconda3/lib/orca_app/orca: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory
 

путь /home/astro/mpisketzis/anaconda3/lib/orca_app/orca действительно существует, так что это как-то странно

Есть какие-нибудь зацепки?
