[BUG] Imviz: module 'zmq.eventloop' has no attribute 'ioloop'

[oyk100]

Installed the jdaviz package into its own new environment following the directions. No issues with the pip installation. However, attempting to load an image gives an error.

from jdaviz import Imviz import matplotlib.pyplot as plt import numpy as np

imviz = Imviz() imviz.load_data("/Users/kargaltsev/Dropbox/Public/jw01478-o014_t003_nircam_clear-f277w_i2d.fits")

Gives a very long Traceback with the final error

File ~/mambaforge/envs/jdaviz-env/lib/python3.9/site-packages/glue_jupyter/utils.py:101, in get_ioloop() 99 ipython = IPython.get_ipython() 100 if ipython and hasattr(ipython, 'kernel'): --> 101 return zmq.eventloop.ioloop.IOLoop.instance() AttributeError: module 'zmq.eventloop' has no attribute 'ioloop'

Hello and thanks for the report. I am afraid this might be an upstream issue:

• https://github.com/glue-viz/glue-jupyter/issues/342

Please downgrade pyzmq to 24.0.1 and let us know if it works.

Yes, it does fix the issue. Thank you!
