Should I install Anaconda (or miniconda) Python?

[Tao Zhang]

Hi Balthasar & all,

   After I installed Anaconda python, previous command "python3" and 
abbreviation does not work anymore (see 1)
   I use .cshrc (see 2) file. I find that .bash_profile is changed (see 3).

  I use "conda deactivate" to exit the Anaconda python, it does not work 
(see 4)

  How can I return to previous state in which .cshrc and associated 
command can work if I do not uninstall the Anaconda python?

  Thanks
  Tao


1) [MacBook-Pro:~] tzhang% python3
python3: Command not found.


2) my .cshrc file
"setenv PATH /usr/local/bin:/opt/local/bin:/opt/local/sbin:$PATH"

3)  .bash_profile  after installing Anaconda python
-------------
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/Users/tzhang/anaconda3/bin/conda' 'shell.bash' 'hook' 
2> /dev/null)"
if [ $? -eq 0 ]; then
     eval "$__conda_setup"
else
     if [ -f "/Users/tzhang/anaconda3/etc/profile.d/conda.sh" ]; then
         . "/Users/tzhang/anaconda3/etc/profile.d/conda.sh"
     else
         export PATH="/Users/tzhang/anaconda3/bin:$PATH"
     fi
fi
unset __conda_setup
# <<< conda initialize <<<

[MacBook-Pro:~] tzhang% conda deactivate
[MacBook-Pro:~] tzhang% python3
python3: Command not found.
