Installation on ubuntu 20.04

[colindaven]

Hi,

I've tried to install on Ubuntu 1804 and 2004. 2004 was successful using

pip3 --user install modbamtools

However trying to use the tools likely picks up the python2.7 on the system and not the python3.8 which is also installed, and therefore can't find the lib listed below.

Any ideas how I temporarily change this eg with PYTHONPATH ? Or could it be another issue ?

Thanks Colin

Hi Colin!

I believe working in a clean python3.8 environment should resolve this! I'm trying to work on a conda release that hopefully will address all this. lmk if that doesn't work!

Thanks, Roham
