not having a Minimum Working Example (post a MWE if this solution doesn’t work) to go off of, I would say its your directory structure here.
You have a root folder with 2 sub-folders names myconfig and main. In
myconfig/ is your python config file and in your
main/ is your Streamlit app python file (a bit of an educated guess here)
Now unless im on my head here, you can’t actually have this type of directory structure (not easily and its “bad” practice to do so) for your modules in Python. Checkout this link for more detail.
Python only looks in the Current Working Directory (CWD), in your case anything in
root/main/ and of course your system path. Python it will not know that
myconfig is one directory above your
main directory. If you change your directory structure to this, it will solve your problem:
Hope this helps!
