Can't execute conda activate from bash script

Good description of the problem in conda github.

Calling conda activate from a bash script will raise some errors:

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.

source ~/your_conda/etc/profile.d/conda.sh

It is just a matter of sourcing the conda bash settings before calling conda activate.

In m case I have installed conda in ~/miniconda3, I just have to call source ~/miniconda3/etc/profile.d/conda.sh

Example to run my blogging environment 

#!/bin/bash
source ~/miniconda3/etc/profile.d/conda.sh
cd ~/git/guillaume/guillaume_blog/_notebooks
conda activate fastai
jupyter notebook
