conda activate not working in a bash file

Question

I am trying to write a script with the name myscrpt.sh, so when I run it it automatically creates a virtual env and activate it using conda. My conda version is 4.7.1.

This is what I have at the beginning of my myscrpt.sh:

#!/bin/bash
conda create --name myenv1
conda activate myenv1

creating the environment is not a problem, however I get the error:

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'.

I don't get this error if I run conda activate myenv1 directly in my terminal.

So far I have taken several measures such as using conda init <SHELL_NAME> which did not help at all. Then I added the following in my bashrc

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

which also didnt work. Next and according to this link changed the path in the PATH line to:

. /opt/conda/etc/profile.d/conda.sh
conda activate base

This one was written for conda 4.4, but I was hoping wouold help me.

Then I tried conda run instead of conda activate, but this also did not help.

So any ideas how can I get this working? :)

UPDATE1: Now I use source ./myscript.sh, and activating works fine, but it gets to errors in conda install.

Answer 1

Either

1. Add eval $(conda shell.bash hook) to your script, or
2. Call your script with bash -i to invoke your interactive environment

Answer 2

Another answer, given in this question that worked for me on this error message was:

source activate base

So a full example could be:

#!/bin/bash
conda create --name myenv1
source activate base 
conda activate myenv1

Answer 3

On Ubuntu Focal, this is the only method that working for me.

Assuming that your envs are installed in ~/miniconda3 directory.

source ~/miniconda3/etc/profile.d/conda.sh
conda activate myenv

Answer 4

I had same issue but this worked : in terminal Type:

$ bash
$ conda init
$ cd /path_that_include_env_dir
$ conda activate ./<env_name>

or

$ conda activate /env_path

"env_path" is full environment path as : /home/usr/env_dir

To check environments list and their paths

$ conda env list
