cuDNN Release Notes v7.5.1

Key Features and Enhancements

The following features and enhancements have been added to this release:

Fixed Issues

The following issues have been fixed in this release:

  • In cuDNN 7.5.0, using the static link for cudnnConvolutionBiasActivationForward() function may result in CUDNN_STATUS_NOT_SUPPORTED error message. The workaround is to perform a whole-archive link. This issue is fixed in cuDNN 7.5.1.
  • In cuDNN 7.5.0 and 7.4.x, in some cases of input images with large dimensions, the 3D forward convolution operations with CUDNN_CONVOLUTION_FWD_ALGO_IMPLICIT_PRECOMP_GEMM will cause a crash with “illegal memory access” error. This is fixed in cuDNN 7.5.1.
  • In cuDNN 7.5.0, setting attnDropoutDesc=NULL in cudnnSetAttnDescriptor() triggered a segmentation fault in cudnnMultiHeadAttnForward(), even though the user is required to set it to NULL in the inference mode. This is fixed in cuDNN 7.5.1.

Known Issues

The following issues and limitations exist in this release:

  • In cuDNN7.5 and cudnn7.5.1, image size smaller than filter size is unsupported, even with sufficient padding.
