+You probably don't want to type the //source// line each time you need to use your conda based python, so you can add a ''source  ~jypeter/.conda3_jyp.sh'' line in your ''~/.bashrc'' file, and ''source  ~jypeter/.conda3_jyp.csh'' line in your ''~/.cshrc'' file. Then, when you need a specific python environment, just type ''conda activate name_of_the_specific_environment''
