[bug] conda: command not found

installing on a python pip environment that was not installed via conda throws an error

logs :
```bash
Setting conda init...
./install.sh: line 40: conda: command not found
./install.sh: line 41: /etc/profile.d/conda.sh: No such file or directory
Setting environment... (envs/environment.yml)
./install.sh: line 48: conda: command not found
Activating environment... (klaam)
./install.sh: line 51: conda: command not found
Upgrading pip...
./install.sh: line 55: python: command not found
Updating poetry config...
./install.sh: line 59: python: command not found
Installing dependencies using poetry...
./install.sh: line 62: python: command not found
```

Start by reading install.sh around lines 40-62 and envs/environment.yml to understand the conda and Python assumptions. Reproduce the installation in a pip-only environment, then verify that the installer handles that environment without the reported conda and python command-not-found errors.
