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'.
$ conda init --help
usage: conda init [-h] [--all] [--reverse] [--json] [-v] [-q] [-d]
[shells [shells ...]]
Initialize conda for shell interaction. [Experimental]
Options:
positional arguments:
shells One or more shells to be initialized. If not given, the
default value is 'bash' on unix and 'cmd.exe' on Windows. Use
the '--all' flag to initialize all shells. Currently
compatible shells are {bash, fish, powershell, tcsh, xonsh,
zsh}
optional arguments:
-h, --help Show this help message and exit.
--all Initialize all currently available shells.
-d, --dry-run Only display what would have been done.
setup type:
--reverse Undo past effects of conda init.
Output, Prompt, and Flow Control Options:
--json Report all output as json. Suitable for using conda
programmatically.
-v, --verbose Use once for info, twice for debug, three times for trace.
-q, --quiet Do not display progress bar.
Key parts of conda's functionality require that it interact directly with the shell
within which conda is being invoked. The `conda activate` and `conda deactivate` commands
specifically are shell-level commands. That is, they affect the state (e.g. environment
variables) of the shell context being interacted with. Other core commands, like
`conda create` and `conda install`, also necessarily interact with the shell environment.
They're therefore implemented in ways specific to each shell. Each shell must be configured
to make use of them.
This command makes changes to your system that are specific and customized for each shell.
To see the specific files and locations on your system that will be affected before, use the
'--dry-run' flag. To see the exact changes that are being or will be made to each location,
use the '--verbose' flag.
IMPORTANT: After running `conda init`, most shells will need to be closed and restarted
for changes to take effect.
