Got this error while working on this project: https://github.com/zhou13/neurvps
Please help us resolve it ASAP

Start by tracing the call from eval.py through neurvps/models/vanishing_net.py and neurvps/models/deformable.py, where the DCN extension is loaded. Reproduce the Windows failure and determine the supported build prerequisites or handling for the missing cl compiler; done means the extension loads successfully for the reported evaluation path.
