About encountering exception while using ConvTranspose2d in nni pruning

[ChristopherCao]

Describe the issue:
Report an bug.

When using ConvTranspose2d in config_list to prune my models, I encountered an exception: Unsupported types for ConvTranspose2d.
However, when I check the library files, I see this

in nni/compression/speedup/mask_conflict.py, it deals with ConvTranspose2d here,
whereas does not deal with ConvTranspose2d here, which leads to exception for anyone who uses ConvTranspose2d in their codes

However, I have no idea to solve this by coding myself, so I report a bug here.
Hope to see the solution ASAP, thanks!
