Can't find python inside the docker container

[ArghyaChatterjee]

Hello,

Thanks for your work. I tried to run the docker container and it was built correctly on a ubuntu 20.04 pc with cuda11.3. When I tried to run the docker run command, it's running the recently built docker image perfectly fine but when I tried to execute the following commands inside the docker container, I see it can't detect any python interpreter inside docker.

arghya@arghya-Pulse-GL66-12UEK:~/LabelMaker$ docker build --tag labelmaker-env-20.04 -f docker/ubuntu20.04+miniconda.dockerfile .
arghya@arghya-Pulse-GL66-12UEK:~/LabelMaker$ docker run   --gpus all   -i --rm   -v ./env_v2:/LabelMaker/env_v2   -v ./models:/LabelMaker/models   -v ./labelmaker:/LabelMaker/labelmaker   -v ./checkpoints:/LabelMaker/checkpoints   -v ./testing:/LabelMaker/testing   -v ./.gitmodules:/LabelMaker/.gitmodules   -t labelmaker-env-20.04 /bin/bash

What's the problem here ?
