I'm trying to execute trains-agent in docker mode with conda as package manager, is it supported?
It should, that said we really do not recommend using conda as package manager (it is a lot slower than pip, and can create an environment that will be very hard to reproduce due to internal "compatibility matrix" of conda, that might be changing from one conda version to another)
"trains_agent: ERROR: ERROR: package manager "conda" selected, but 'conda' executable could not be located"
This means that the conda package manager does not exist in the docker itself. In most case you can use pip, it will find most of the python packages, and since you are using dockers, you can always select the one with the correct cuda version to match your Tensorflow (if you are using pytorch, trains-agent will automatically pull the correct pytorch version based on the installed cuda version inside the docker)
