Problem description:

When I use armnn to do inference on my mobile device with ssd_mobilenet_v3_small_coco. It stuck in this function . clEnqueueMapBuffer No error code, just can't return. You can find the model here:

https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf1_detection_zoo.md

Any help?

If I don't add these flags: -Wno-type-limits -Wno-strict-overflow, ACL can't be compiled.

Hi @steven9046

Could you please upgrade to the latest release of ACL (v22.02) and let us know if you still experience the problem ?
