In your Python environment, what does running cocotb-config --libpython give you?

from cocotb.

/conda/conda-envs/tek/lib/libpython3.10.so.1.0

from cocotb.

Are you setting LIBPYTHON_LOC environment variable to that path?

from cocotb.

yep:
echo $LIBPYTHON_LOC /conda/conda-envs/tek/lib/libpython3.10.so.1.0

from cocotb.

Is cocotb installed from pypi or did you build it locally?

from cocotb.

From using conda. in the conda env file we have this
`
name: tek
channels:

• conda-forge
  dependencies:
• numpy
• python=3.10.8
• pyqt=5.12.3
• sphinx
• pip
• numpy
• python-gitlab
• pymongo
• pip:
  • watchdog
  • python-constraint
  • PyYAML
  • elasticsearch>=7,<8
  • cocotb
  • cocotb_coverage
  • pyvsc==0.8.7.6990678536
  • pytest
  • pyuvm
  • systemrdl-compiler
  • /proj_tensix/user_dev/pymodules/pysqlite3
    `

from cocotb.

At this point, I'll point you to https://docs.python.org/3.10/c-api/intro.html#embedding-python which has some details on how the embedded Python interpreter determines search paths.

We may look at using Py_InitializeFromConfig for Python 3.8+.
