conda installation

[mahmud1]

Currently, the environment.yml file contains all dependencies, including runtime and development dependencies. I propose separating the development dependencies.

Suggested Action:

• Create a new file environment_dev.yml containing all runtime and development dependencies.
• Remove all development dependencies from environment.yml.
• Update any relevant documentation to reflect this change.
