mamba: command not found

Mamba is a high-performance Python package manager that provides a more intuitive and blazing-fast experience compared to the standard `pip`. It's built specifically for conda environments, which are widely used in scientific computing and data analysis. Mamba is designed to speed up the installation and management of packages by caching information and optimizing package resolution.

When you encounter the "command not found" error for `mamba`, it typically means that your system isn't aware of the mamba executable or that the installation of mamba is incomplete. Here's how you can troubleshoot:

1. **Install mamba**: If you haven't installed mamba yet, you can do so by installing miniforge, a lightweight version of Anaconda. Download and run the installer from <https://docs.conda.io/en/latest/miniconda.html>, then activate the environment and install mamba using `conda install -c conda-forge mamba`.

2. **Add to PATH**: Make sure that the directory containing the mamba executable is added to your system's PATH. This usually happens automatically during installation, but you may need to manually edit your `.bashrc` or `.bash_profile` file if necessary.

3. **Check installation**: After installation, run `which mamba` in your terminal to see if it returns the path to the executable. If it doesn't, check the installation location and add it to your PATH.

4. **Reinstall**: If you've already installed mamba but still get the error, try uninstalling and reinstalling.
