GL ES 2.0 error

[z-lumley]

Hi, I have installed PlantSeg using the instructions.

I ran into the same problem as adkrishnan in issue #274 and used their solution to install bioimageio.core

That solved that issue, however when attempting to run plantseg --napari or plantseg --gui I get the following error:

plantseg --napari
You are using the latest version of PlantSeg: 1.8.1.

Any advice or suggestions would be appreciated!

Hi @z-lumley thanks for reporting. Are you using a Mac?

Hi @qin-yu, I'm using Ubuntu 22.04 through WSL

I reviewed your issue again. It seems that during Napari's import of Layer, vispy throws an error saying GL ES 2.0 library not found. This is very unlikely to be a PlantSeg issue. If you followed the recommended installation step, conda or mamba should have installed the dependencies correctly unless there are bugs in some packages of specific versions.

@lorenzocerrone am I right?
