Hi,

I'm facing build error while installing cutorch. Can someone help?

HI,

Do you have CUDA properly installed? If so, you may have installed it in a non standard path and you want to specify where it is with CUDA_TOOLKIT_ROOT_DIR.

Cuda is not installed on my system. I have tried installing using the command. However, it's giving me below error. can someone please help me? I want to work with deepmask and sharp mask. I heard that it works with CUDA version 7.0 or lower only..I'm not sure.
