nvcc致命的：安装CUDA 8.0时不支持的gpu架构“ compute_61”

Question

I have a problem while installing cutorch with luarocks. The error announces that gpu architecture 'compute_61' is not supported. After some search I figured out that the problem can be caused by old CUDA version. But it is not the case since I have CUDA 8.0

sudo ~/torch/install/bin/luarocks install cutorch

what could be the problem?

Answer 1

In cmake checks at the beginning of installing cutorch you have:

-- Found CUDA: /usr (found suitable version "7.5", minimum required is "6.5")

It looks like you have two CUDA versions installed -and 7.5 is picked by the installer. Another option is that installer doesn't support 8.0 .

Answer 2

Thanks to everybody who replied. Finally the problem was resolved by reinstalling Torch AND (what I guess might be the reason) updating cudnn (from version V4 to V5).

Answer 3

I had something similar ( compute 70 ). I think it was because I upgraded my ubuntu distribution (16.04 --> 18.04) and cuda 8.0 is not supported for ubuntu 18.04. I uninstalled cuda 8.0, installed cuda 10.1, and the problem seems to have gone away.

Caveat: I was trying to solve the problem a few different ways, and this was the last thing I tried before it worked. Technically it could have been one of the intermediate steps that solved the unsupported gpu architecture error, but I can't go back and check now.
