On MacOS versions 10.13 and older, install fails due to
This can be fixed by reinstalling scikit-image:
pip uninstall scikit-image conda install scikit-image
The reason for this issue is that prebuilt binaries for
work on Mac versions of 10.13 or older and conda installs an older
version of scikit-image that works with those versions.
Another way to get the up-to-date
scikit-image version is:
pip install -U --no-binary scikit-image scikit-image.
Although this solution takes much longer (~5 minutes) to install than the first solution.
On some platforms, install fails due to
The 0.6.4 version of
vispy fails to build for some combinations of
platform/OS and Python versions.
vispy 0.6.5 has resolved this, but a
workaround if you have an older version of vispy is to ensure you have a
% conda create -n jdaviz python=3.8 % conda activate jdaviz % pip install vispy>=0.6.5 % pip install jdaviz –no-cache-dir

Collapse Plugin spectral bounds don’t match selected region¶
Spectral bounds are off in the plugin compared to the spectrum viewer.
Ghost subsets and models in spectrum viewer¶
Mysterious extra subsets and models appear in the Specviz spectrum viewer after fitting a model. Pan/zoom and resize were also used, but it is unclear if they play a role or not in this bug.
Cubeviz Collapse and Moment Maps: Spectral bounds do not match Region selection¶
When trying to do a second collapse with the same spectral region, but with resized bounds: change to Region=None, resize the region, then reselect Region 1, the region bounds are correct. However, applying Collapse again, it errors out and the image viewer that contained the intial collapse goes blank.
Cubeviz cube viewer colormap printed out¶
When changing the colormap in the Cubeviz cube viewer–>Layer–>colormap, the colormap name is printed in the cell output.
Cubeviz cube viewer contrast changes when collapsing jupyter scroll window¶
In order to see the full Cubeviz app in a Jupyter notebook, one can click on the side of the cell output to collapse or expand the scrollable window. This has the unintended consequence of changing the contrast of the image displayed in the Cubeviz cube viewer.
