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.

從 how-to-use-azureml/track-and-monitor-experiments/using-mlflow/train-projects-local/train-projects-local.ipynb 開始，尤其關注包含 {“USE_CONDA” : True} 的最後一個程式碼區塊。執行 notebook，並檢查該區塊執行時使用的是哪個 conda 環境。當範例執行時不出現 ModuleNotFoundError: No module named ‘sklearn’，並且使用為 MLFlow 專案建置的環境時，即表示完成。
