如果在AI Studio的Paddle 2.0.2环境，使用PaddleX的命令行工具的下列命令切分数据集

paddlex --split_dataset --format VOC --dataset_dir MyDataset --val_value 0.2 --test_value 0.1

会产生报错，报错信息为：

/opt/conda/envs/python35-paddle120-env/lib/python3.7/site-packages/paddle/fluid/layers/utils.py:26: DeprecationWarning: `np.int` is a deprecated alias for the builtin `int`. To silence this warning, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
Deprecated in NumPy 1.20; for more details and guidance: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
