Undefined symbol while importing so. file

Question

I was running a code of (https://github.com/google-deepmind/constrained_optidice) for research purpose. When I tried to run neural/run_experiments after installing the requirements as stated, it gave me an error of

envs/cop/lib/python3.7/site-packages/courier/python/py_client.so: undefined symbol:_ZN4absl12lts_2021110214ascii_internal13kPropertyBitsE

The code block where error arises is:

from courier.python import py_client

where courier.python is directory and py_client is .so file.

I tested it with ubuntu 20.04 and 22.04 but both did not work. I am not 100% sure but i saw this error arises when there is a conflict of unpackaging c-wrapped file (.so file). However, I tried with different gcc and g++, it did not work neither.

I am using miniconda3 with python version==3.7.16 with Ubuntu 22.04 and the error occurs from the library dm-launchpad-nightly. Can anyone help with this?

directory where error arises

It's a problem with the dependencies; I didn't manage to solve it myself, but stumbled on this github issue with requirement.txt file with the correct dependencies.
