Please always share the complete traceback. Particularly for this type of error, the part that was omitted contains the key information needed to diagnose and recommend a solution for this issue.
In addition, you should share it in a code block, like this:

Something appears to be broken with your install of the psycopg2 package. If you installed this copy of Python yourself (as I think the fact it is under usr/local suggests you might have), I suggest doing python3.6 -m pip install --force-reinstall psycopg2 to reinstall and hopefully fix it. If that doesn’t work, you can (and usually should) create a virtual environment and install the packages you need there, with
python3.6 -m venv your-env-name
source your-env-name/bin/activate
pip install <the packages you need>
# Etc.
Also, just FYI, Python 3.6 just officially went out of support upstream, and the latest pip 22.0 dropped support for it. Perhaps not an immediate issue, but if you control your installed Python, its probably time to start thinking about upgrading.
Also FYI, for the future, your traceback still wasn’t formatted correct as I instructed above. You can see how it looks in the preview window to the right; if it doesn’t look like my example, it is not correct. In the future, you can simply copy and paste my example, and then paste your traceback inside of it.
tried installing as suggested by you… python3.6 -m pip install --force-reinstall psycopg2
