Subject [GitHub] [singa] chrishkchris edited a comment on issue #552: SINGA-496 Implement softplus and softsign functions for tensor math

chrishkchris edited a comment on issue #552: SINGA-496 Implement softplus and softsign functions
for tensor math
URL: https://github.com/apache/singa/pull/552#issuecomment-553887595
 
 
   This is the build log. We can see the missing codes from the log.
   Since you put cuda::softsign(num, inPtr, outPtr, ctx->stream); in tensor_math_cuda.h,
you will need to add it the header in math_kernal.h and the cuda computation part in math_kernal.cu
   Thanks!
