+If you face memory issues in traning, you can lower the `batch_size` in the configurations to reduce the System RAM requirements.

 ### Inference on a WSI
 
 Inference is performed on WSI in a sliding window manner with specified stride. A foreground mask is needed to specify the region where the inference will be performed on, given that background region which contains no tissue at all can occupy a significant portion of a WSI. Output of the inference pipeline is a probability map of size 1/stride of original WSI size.
