I was provided with an environment.ubuntu.yml file to be able to create a conda environment. However, running conda create env --file environment.ubuntu.y
I have met this issue and solved it. Firstly, I made my anaconda version to be consistent with where the yaml file export from. This may be useless but i consider that consistent conda version can promise consistent base environment. Secondly, i deleted all dependencies but some 'main' packages which are i actually want to use in my yaml file.That means let these 'main' package handle dependency issues.
