Subject [GitHub] [singa] chrishkchris opened a new pull request #709: Update CUDNN from 7.3.1 to 7.6.5
Date Mon, 25 May 2020 04:52:38 GMT

chrishkchris opened a new pull request #709:
URL: https://github.com/apache/singa/pull/709


   I see some other frameworks have updated their cudnn to 7.6.
   
   Our cudnn version is quite old, so I modify the version of cudnn from 7.3.1 to 7.6.5 (in
conda env as well as docker env). Therefore, when we do performance analysis, we can base
on same/similar version of cudnn.
   
   Meanswhile, the speed seems does not change, compared in panda13 (cuda 10.2).
   
   (i) cudnn 7.3.1
   ```
