Set the input and output tensors.
[in] | src | Source tensor info. Data types supported: QASYMM8/QASYMM8_SIGNED/F16/F32. |
[out] | dst | Destination tensor info. Data types supported: same as input . |
[in] | beta | A scaling factor for the exponent. |
[in] | is_log | True if the operation is log-softmax |
tmp | Auxiliary tensor info. Must be type F32 and same shape as the input. |
TODO: Check dimensions > 0 for holes only. For this, we need a utility function checking if there are holes after some dimension.
