The downside is that whatever you’re doing when your program begins, the xwindow system has not yet initialized and also you get that error. I’m making an attempt to run a python GUI program on Raspberry Pi 3 on startup in terminal. If someone may help me with this error, it might be actually helpful. Tk will normally create GUI on your interface. But Colab is run on the web server in the cloud. It can’t open a window on your machine.
Or when hook up with server use ssh -X remoteMachine command to make use of Xwindows. Once you’ve that, you can begin tackling the Catalyst-specific errors, in order you’ll find a way to see this is mostly unrelated to Catalyst. If your client is Windows, you’ll need an occasion of an Xserver installed and configured to display the remote home windows regionally. In Linux that comes by default, in Mac you need one thing like XQuartz, and in Windows something like Cygwin. This is an error that you simply might make while operating the python script.

Do you have an Xserver/GUI surroundings installed on the Ubuntu server?
Now Search log occasions and configuration files using AJAX and a browser. Still grepping by way of log files to search out problems? You do not explain how you’re doing the autostart.

You can remedy it by including these two strains within the VERY beginning of your .py script. Share a hyperlink to this query via email, Twitter, or Facebook. This is the total error I’m getting whereas I run the program via CLI.
