Environment

  • libtorch version win-cu90-1.1.0
  • cuda-driver 10.1
  • gpu devices GTX1080 and RTX2070 (on one computer)

Description

on gtx1080, the trace-model can be loaded through jit, but an error occurs on rtx2070,it says fatBinaryCtl_CreateHandle can not be located on C:\WINDOWS\system32\nvcuda.dll. I have tested successfully on notebooks with GTX1060,GTX965M,GTX920M,GTX960M,GTX940MX. The issue looks like has something to do with the cuda-driver or the new RTX card ?

any device or help ? thank you.

nvcuda.dll is managed by your GPU driver. Please keep them constant between devices.

Wait, I just noticed you are using CUDA 9.0 binaries for RTX cards. I'm afraid you 'll have to use the CUDA 10.0 one instead.
