Link error which i could not fix

[mesut92]

Did anyone test this algorithm on Ubuntu?I am trying to run, but i got stuck one point and i could not fix it. Which versions should i use Ubuntu, python, Cmsis, tensorflow, gcc and g++ or etc... for this repo? I tried different versions, and tried refresh the conda, but it did not work.

here is the error which i got;
