来自mlflow 文档

MLflow要求conda在项目特性的路径上。

试着遵循下面的说明：

# Install MLflow
pip install mlflow

# Install MLflow with the experimental MLflow Pipelines component
pip install mlflow[pipelines]  # for pip
conda install -c conda-forge mlflow-pipelines  # for conda

# Install MLflow with extra ML libraries and 3rd-party tools
pip install mlflow[extras]

# Install a lightweight version of MLflow
pip install mlflow-skinny
