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.
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 runningecho $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).
