When running retinaface test_widerface.py, cudnn autotune repeats.

src/operator/nn/./cudnn/./cudnn_algoreg-inl.h:97: Running performance tests to find the best convolution algorithm, this can take a while... (setting env variable MXNET_CUDNN_AUTOTUNE_DEFAULT to 0 to disable)

And setting the MXNET_CUDNN_AUTOTUNE_DEFAULT to 0 is not working, any clues?

[Edwardmark]

in the R50-symbol.json file, reset param cudnn_tune's value with "None" would help. the default value of cudnn_tune is limited_workspace.
in vim run：
:%s/"cudnn_tune": "limited_workspace"/"cudnn_tune": "None"/g
can solve the issure.

@Edwardmark , after replacing cudnn_tune:"None", my program still does not work. Do you have any other advice? Thanks

Try replacing "cudnn_tune": "limited_workspace" with "cudnn_tune": "None" AND setting env variable MXNET_CUDNN_AUTOTUNE_DEFAULT to 0. You need to do both to get rid of this issue.

@Zheweiqiu you are totally right, thank you, guy!
