ImportError: Cannot load backend 'TKAgg' which requires the 'tk' interactive framework, as 'headless' is currently running

Hi,
When running TADtool using an iced matrix file and its corresponding bed file, generated from the HiC-Pro pipeline, I get the following error.

How can I fix it? Thanks!

Hi, sorry about the late reply. This error implies that you are running TADtool in an environment that does not support interactive plotting, typically a computing cluster or similar. Please install TADtool on a machine that supports it and try again.

Hello @kaukrise,

I work with the Linux system, and I encountered this error as well.
I tried using JupyterLab, but I still encountered the same problem.
Could you give me any advice?

Thanks
Han
