could you please look into the issue?

There's no template.json for the Miner Rule analytic.

When I run the two step orchestration, there's error:
outputCDM, sensor1Stress and sensor2Stress are needed in the Miner Rule calculation but data are not provided in the initial TimeSeries data. Also they're not defined in the asset model.json

Which signals are the output of calculation, it seems not defined in assets.

For Python analytics, within the config.json file, is there a way to add or modify the Python channels that search for package dependencies?

Within a standard .condarc file for Python, developers can add custom channels. This is especially useful for packages that are not available from the open source community.
