Describe the bug
The code from A U-Net model for lung lesion segmentation from CT images could not be runned.

The error information is: TypeError: __init__() got an unexpected keyword argument 'to_onehot_y'.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://github.com/Project-MONAI/tutorials/tree/master/3d_segmentation/challenge_baseline/
2. Install MONAI by pip install monai. NOTE: this is important. Different install methods lead to different errors TypeError: __init__() got an unexpected keyword argument 'to_onehot_y' #60
3. Run commands python run_net.py train --data_folder "COVID-19-20_v2/Train" --model_folder "runs"

Expected behavior
Start training of the model.

thanks for reporting, that baseline script won't work with pip install monai at the moment, because we haven't included it in the milestone release.
