Seems that THCudaBlas_Sgemv has been moved to at::cuda::blas::gemv. But after compiling the dcn with the new API linkage error shows up like undefined symbol: _ZN2at4cuda4blas4gemvIfEEvcllT_PKS3_lS5_lS3_PS3_l  . After going through torch repo i couldnt find the definition of at::cuda::blas::gemv anywhere. Am I missing something??
