human-constraint.ipynb: RecursionError: maximum recursion depth exceeded

[hyosilpro]

An error occurred in the module below. I used the current version uberon 2021.02.13. But when I used the old version you provided 2015-07-24 Uberon release, there is no error.

The error message is:

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

      8         if key in out_keys:

RecursionError: maximum recursion depth exceeded
-------------------------------------------------------------------------------------------------------

The error message was as follows, and I tried several things, but it didn't work. What should I do?

-------------------------------------------------------------------------------------------------------
import sys
sys.setrecursionlimit(30000)
print(sys.getrecursionlimit())
-------------------------------------------------------------------------------------------------------
The kernel for  human-constraint.ipynb appears to have died. It will restart automatically.
-------------------------------------------------------------------------------------------------------

Kindly regards

Sounds like there is a cycle in the graph. The 2021-02-13 Uberon must not directed acyclic for the union of the is_a, part_of, develops_from relations.

What if you remove develops_from from in_keys?

[hyosilpro]

I did remove develops_from from in_keys, but same error has occured.

so, I download human subset.

following link data set
http://uberon.github.io/downloads.html#subsets

https://raw.githubusercontent.com/obophenotype/uberon/master/subsets/human-view.obo

And then the problem was solved.

Ah, nice to see that Uberon now has a human view. This wasn't around when we made human-constraint.ipynb, such that you probably don't need human-constraint.ipynb at all anymore. Since now you can just use human-view.obo as the input ontology for process.ipynb.

When I checked the code, it was determined that as you mentioned. just start ' process.ipynb` .
Thank you very much for your reply.
