Module use of python34.dll conflicts with this version of python

I am using the “SEN-ET” plugin to estimate the reflectance and transmittance of leaves ,but there is an error “module use of python34. process exited with value 1 finished tool execution in 1 seconds”, how should I fix it?
I used snap 3.8 and python 3.4

Your Python version is incompatible. You should have Python 3.6.

Thank you very much for your answer :grin:
