which version of Moco is implemented

[nikky4D]

is there a way to choose which moco version I want to use? or is moco v2 the moco version implemented in the repo? And, how would I load the official moco pretrained model/encoder weights (from https://github.com/facebookresearch/moco/tree/78b69cafae80bc74cd1a89ac3fb365dc20d157d3) as my pretrained weights?
