Opening display from a script

[wsnoble]

I've got higlass working from within a Jupyter notebook, but the same code gives an error when I run it from a script. Is there something different that needs to be done for non-jupyter notebook usage?

Here is the error:

Process Process-1:
Traceback (most recent call last):
  File "/Users/wnoble/opt/anaconda3/envs/ppx/lib/python3.9/site-packages/multiprocess/process.py", line 315, in _bootstrap
    self.run()
  File "/Users/wnoble/opt/anaconda3/envs/ppx/lib/python3.9/site-packages/multiprocess/process.py", line 108, in run

    raise KeyError(key) from None
KeyError: 'WERKZEUG_SERVER_FD'

And here is the code:

            my_array = sparse_matrix.toarray().astype(float)

            ts = Tileset(
                tileset_info=lambda: npmatrix.tileset_info(my_array),
                tiles=lambda tids: npmatrix.tiles_wrapper(my_array, tids)
            )

            display, server, viewconf = higlass.display([
                View([
                    Track(track_type='top-axis', position='top'),
                    Track(track_type='left-axis', position='left'),
                    Track(track_type='heatmap',
                          position='center',
                          tileset=ts,
                          height=500),

                ])
            ], fuse=False)
            display

I am running this on MacOS 12.5.1.

Have your issue been resolved? I am facing the same problem.

+1 Same issue here.

+1, I tried different versions of WERKZEUG too, but I am getting the same error.

I ran into the same problem, then I tried to downgrade my WERKZEUG to version 2.0.3, and it worked for me.
