I'm using fish shell (on mac) which is unfortunately not compatible with bash syntax, so instead of sourcing it, you need to start the setup with: bash setup_conda.sh. Then you will want to add the following line to the $SHELL case switch: /usr/local/bin/fish*) SHELL_NAME=fish ;; (for me fish is at /usr/local/bin/fish, check your location by running echo $SHELL). This ensures that later the conda init line will be invoked with fish as last param.
The .bashrc lines are not doing any harm on a fish system (don't have a .bashrc so .condainit will be empty and sourcing it will do nothing)
Finally I had to change the last line to conda install mamba -c conda-forge (as specified in mamba's installation guide), should not be a fish specific thing though as far as i can tell? Without specyfing conda-forge as a channel that installation failed on my machine.
And when you say "to install fastai with mamba…run" you are I think forgetting to tell users to alias conda to mamba (i know you did on twitter, but people might not have seen that coming here).
Thanks for sharing Jeremy! I had an error "setup_conda.sh: line 34: source: .condainit: file not found." My OS is Centos 7. I was able to fix the issue by switching the command to "source ~/.condainit"
Just a quick note for anyone using Ubuntu in WSL2, don't delete your ~/anaconda3 folder if you want to start fresh. Everything is broken now :(.
It seems like a great idea for managing environments. But the script seems not to be working anymore. After the miniconda install (seemingly after running the condainit script it creates), it stops, saying:
==> For changes to take effect, close and re-open your current shell. <==
Also, if I then try to run conda install -y mamba it appears not to find it in the provided channels (the current documentation recommends conda-forge?)
Leaving this here just in case: I finally added the channel manually: conda config --append channels conda-forge, after which I was able to run
conda install -y mamba
mamba is no longer needed -- I've now updated the gist to reflect that. I've also added a link to a somewhat more official version that's in fastsetup.
NB: You probably don't want this gist any more. Instead, use this version from
fastsetup:To install fastai, once you've run this, run:
NB: If you've installed Anaconda or miniconda before, and you want to start with a fresh install, remove (or rename) your existing
~/anaconda3or~/miniconda3directory before you run this script.
