Trouble running InstaPy quickstart

Question

I was able to install InstaPy on an Oracle Ampere Compute VM (ARM processors) running Ubuntu 20.04 LTS. When I try running quickstart.py, it showed me the following errors:

/usr/lib/python3/dist-packages/requests/__init__.py:89: RequestsDependencyWarning: urllib3 (1.26.8) or chardet (3.0.4) doesn't match a supported version!
  warnings.warn("urllib3 ({}) or chardet ({}) doesn't match a supported "

During handling of the above exception, another exception occurred:

I had to install an older version of the geckodriver meant for ARM processors and /usr/local/bin/geckodriver is executable and present in PATH. How do I resolve this?

EDIT: This is what it shows for echo $PATH

ubuntu@oracleampere:~$ echo $PATH
/home/ubuntu/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/bin/geckodriver
ubuntu@oracleampere:~$ geckodriver
-bash: /usr/local/bin/geckodriver: No such file or directory
ubuntu@oracleampere:~$

I finally got this to work but not on the Oracle Ampere Compute VMs. Apparently it does not want to work with ARM processors. I setup a standard ubuntu box running on Intel processors and that worked.
