insufficient output in Traceback of python execution - python

How to further troubleshoot Django issue where only built-in package files are listed in traceback output, instead of those user-created files, which does not tell what is wrong in the *.py files I created.

RecursionError: maximum recursion depth exceeded while calling a Python object
Any thoughts on how to further troubleshoot?

You have not added the code.
Also the code already explained what's happening there. You are using wagtail decorator, you have to check how the decorator method works.
The error starts from last one
File "/usr/local/lib/python3.7/site-packages/wagtail/utils/decorators.py", line 29, in __get__
return self[owner]
I notice your issue is with threading and I guess you handling with large dataset or file.
Here you can increase the rate
import sys, threading
sys.setrecursionlimit(10**7) # max depth of recursion
threading.stack_size(2**27) # new thread will get stack of such size

See? it would not let me know where is my fault is.
The error suggests that you have forgotten quotes when naming a URL pattern.
For example you have name=my_view,
url('^my-url/$', my_view, name=my_view)
when you should use a string name='my_view':
url('^my-url/$', my_view, name='my_view')

Can you please tell me where I am going wrong?
BTW, my psycopg2 is working fine as a standalone module.
this statement solved everything: export DYLD_LIBRARY_PATH=''
You have to be more precisely with your Question.
First of all, your error is :
ImproperlyConfigured: Error loading psycopg2 module
When do you get this error? (what command you run?)
What is your settings.py looking like?
Also you should format your Question better, it's a pain to read this Traceback!
I know this is more a comment then an answer, but i don't had enough reputation for that.

Python, Django - loaddata issue "RemovedInDjango18Warning"

Anyone know help me?
This looks like it's caused by files being collected by collectstatic having outrageously inaccurate last modified timestamps (like before 1970). Try searching google for tools that allow you to modify your files' last modified dates and change them to something reasonable.
I discoreved.
This is just cause I put some fonts in /static/fonts/ and the django don't accept fonts on Static Folder. So, i changed this files to /media/fonts/.
Worked! :D
