AgitatedDove14 DM's you the log file for the failed task. I have tried using a task startup script to install G++, gcc etc. but it didn't seem to work, I'll try build-essentials too. I'm also interested in the way that the environments are set up in clearml, I read in the docs that the task looks for a requirements.txt file to construct the env, but does this prevent a local package being built correctly i.e. through setup.py when running a remote task?
