The Problems of Conda
Problems
See this link: https://www.reddit.com/r/MachineLearning/comments/myl8yn/d_is_anaconda_worth_the_trouble/.
I have experienced problems with conda, and others have discussed similar issues.
Over time, you become unaware of the different environment settings. So, I had to delete the others. Now, I mainly use Python 3.10.9 and occasionally Python 3.11.11. However, I seldom use even Python 3.11.11. Personally, I don’t need too many environments. I just need one or two to run what I am currently researching or learning.
I prefer a simpler solution. If I have two projects that conflict with each other, I’d rather use one and forgo running the other.
For instance, encountering the following problem is a real hassle. 1
conda config --set proxy_servers.http $HTTP_PROXY
conda config --set proxy_servers.https $HTTP_PROXY
Although setting a proxy for conda initially seemed to speed things up, I ultimately decided to remove it.
Removal
rm -rf ~/anaconda3
rm -rf ~/.condarc
rm -rf ~/Library/Caches/pip
# update ~/.zprofile
# update ~/.bash_profile
~/.bash_profile:
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/Users/lzwjava/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/Users/lzwjava/anaconda3/etc/profile.d/conda.sh" ]; then
. "/Users/lzwjava/anaconda3/etc/profile.d/conda.sh"
else
export PATH="/Users/lzwjava/anaconda3/bin:$PATH"
fi
fi
unset __conda_setup
# <<< conda initialize <<<
And it still showed:
% which conda
conda () {
local cmd="${1-__missing__}"
case "$cmd" in
(activate | deactivate) __conda_activate "$@" ;;
(install | update | upgrade | remove | uninstall) __conda_exe "$@" || return
__conda_reactivate ;;
(*) __conda_exe "$@" ;;
esac
}
After restarting iTerm2, I decided to switch to Homebrew’s Python installation. It seemed like there were multiple Python installations on my computer; I already had six, as shown below.
- ~/Library/Python/3.9
- ~/Library/Python/3.11
- /opt/homebrew/lib/python3.11
- /opt/homebrew/lib/python3.12
- /opt/homebrew/lib/python3.13
- /opt/homebrew/lib/python3.9
Delete with the command, brew uninstall python@3.11.
Important log.
% brew uninstall python@3.13
Error: Refusing to uninstall /opt/homebrew/Cellar/python@3.13/3.13.1
because it is required by cairo, docutils, ffmpeg, ghostscript, glib, gradle, harfbuzz, imagemagick, libass, libheif, liblqr, maven, openjdk, openjdk@17, pango, poppler, tesseract, wireshark and yt-dlp, which are currently installed.
You can override this and force removal with:
brew uninstall --ignore-dependencies python@3.13
Pip log:
pip3 install -r requirements.txt --break-system-packages
pip3 install --upgrade pip --break-system-packages
