Not sure about the difference between two models

❓ Questions and Help

Hi,

I am just wondering what is the difference between the following two models:

mask_rcnn_R_50_FPN_3x 
mask_rcnn_X_101_32x8d_FPN_3x

I want to use detectron2 with instance segmentation and I am not sure what the difference is.

Thanks for any information
