Train Local MLFLow Project conda env missing packages

When trying to run the example notebook how-to-use-azureml/track-and-monitor-experiments/using-mlflow/train-projects-local/train-projects-local.ipynb, the code in the final code block (the one that has `{“USE_CONDA” : True}`) fails with `ModuleNotFoundError: No module named ‘sklearn’`

It seems the code is trying to use the local conda environment despite specifying it to build one from the MLFlow project.
