| ====== JYP steps for installing Miniconda3 ====== | ====== JYP steps for installing Miniconda3 ====== | ||
| + | ===== Before installing Python on a shared computer ===== | ||
| + | |||
| + | ==== Desperately seeking a specific package ==== | ||
| + | |||
| + | Check if the Python package you are [[https://www.imdb.com/title/tt0089017/|desperately seeking]] is not already installed, before installing your own Python on shared Linux servers, or on a shared cluster !! | ||
| + | |||
| + | * Ask other users who know the local environment | ||
| + | |||
| + | * Read the servers/cluster documentation | ||
| + | |||
| + | * Use ''[[other:newppl:starting#using_module_to_access_optional_programs|module avail [mod_name]]]'' to find out the Python versions available, and then ''module load'' and ''conda list'' to get more information | ||
| + | * e.g. on ''spiritx'': <code>$ module avail python | ||
| + | python/meso-3.8 python/meso-3.9 python/meso-3.10 python/meso-3.11 | ||
| + | $ module avail anaconda | ||
| + | anaconda-meso/2022.10 anaconda3-py/2020.11 | ||
| + | anaconda-meso/2023.09-0 anaconda3-py/2021.11 | ||
| + | </code> | ||
| + | |||
| + | * Lots of Python packages do very similar things. Maybe you can use another installed package... | ||
| + | |||
| + | * If the packages you need are not available, it may be faster and easier to ask the local system administrators if they can install the packages, rather than doing everything yourself | ||
| + | |||
| + | ==== Using a specific Python on a jupyter server ==== | ||
| + | |||
| + | If there is a //jupyter notebook server// connected to your system, but the Python you want to use is not available on the server, follow the [[other:python:starting#using_a_non-standard_kernel|using a non-standard kernel]] instructions, rather than starting your own local server | ||
