What does "type = IMTRv21_5" mean?

[Buling-Knight]

I found it diffcult to understand this two file.
#1 local_configs/base/models/segformer.py
#2 local_configs/base/models/segformer.py
I knew that #1 means the base of #2, but I find the code in file 2:
"backbone = dict(type= ‘mit_b0’)",
and the other code in file 1:
"backbone = dict(type= ‘IMTRv21_5’)",

I wonder what does "type = IMTRv21_5" mean? Please Guide me!

I have the same doubts, and I can not find the definition of IMTRv21_5 in either MMsegmentation's backbone library or in the author's code. Have you solved this problem now?
