Solving environment: failed with initial frozen solve. Retrying with flexible solve.

This message typically appears when there is an issue with the package dependencies in the environment you are trying to solve. The initial attempt to solve the dependencies was unsuccessful, so the solver is now attempting a flexible solve to find a solution that meets the requirements.

You can try the following steps to resolve this issue:

1. Check that you have the latest version of the package manager (e.g. conda or pip) installed.

2. Check that your environment.yml or requirements.txt file specifies the correct dependencies and versions.

3. Try running the package manager with the --no-pin option to allow for more flexibility in the package versions that are installed.

4. If the issue persists, you may need to manually install or update certain packages using the package manager.

5. If none of the above steps work, you can try creating a new environment and installing the required packages from scratch.
