[Tutor] Moving a conda environment to an off-line computer

[Henrique Castro]

Dear colleagues,
Soon I'll start to use one of the powerful computers on my university as a tool in my Ph.D. The computer does not have an internet connection and I need to find a way to install a conda environment on it.
At first I tried to install and set the conda environment that I need in a computer with internet connection and taking care to copy everything in a path that is similar in the off-line computer (i.e I installed everything on /home/henrique/bin/anaconda3 at home and tried to copy everything to /home/henrique/bin/anaconda3 in the off-line computer - with the same .bashrc) but when I run conda I get an error(it works on my home computer):
