qeds in Colab: RecursionError: maximum recursion depth exceeded in comparison

[pjakobsen]

After installation with recommend ! pip install qeds in Google Colab (Python3), I get some strange recursion errors, always variation on the same theme:

import qeds
qeds.themes.mpl_style();

---------------------------------------------------------------------------
RecursionError                            Traceback (most recent call last)

      5 # activate plot theme
      6 import qeds
----> 7 qeds.themes.mpl_style();

     52     plt.style.reload_library()
     53     plt.style.use("qeds")

Running this works like a charm:

import qeds
qeds.data.available()

#qeds.themes.mpl_style();

Thanks for the report. @wupeifan aer you seeing the same thing? Any ideas @sglyon @cc7768 ?

[wupeifan]

Yeah, I can confirm this issue. And it is not the only issue: qeds.themes.plotly_template() also triggers a similar error.
This never happened when we soft-launched. Maybe @sglyon changed something in the latest version of qeds, or there are some package updates that we are not aware of...

Thanks for reporting @pjakobsen

I didn't change anything. Not sure what if anything might have changed from underneath us

[jlperla]

Do we know if this colab only? Haven't seen it with normal builds. Did a backend dependency change on the baseline colab images,and how might we check?

[wupeifan]

Things are well on pims or ubc.syzygy, so I think it is Colab only. If Spencer didn't change anything in qeds (rather just an update in version number) then it could be some dependent packages that have changed I guess...
