Cannot run SSD model on Mac Book Pro using opencl backend

Previously i’ve deploy SSD model to default cpu llvm backend, and now i want to have a try on my Mac Book Pro using Apple’s opencl support.

.so export is ok, but when trying to run detect, i have the wierd error:

/usr/local/lib/python3.8/site-packages/mxnet/gluon/block.py:1512: UserWarning: Cannot decide type for the following arguments. Consider providing them as input:
data: None
input_sym_arg_type = in_param.infer_type()[0]
zsh: abort      python3 deploy_ssd_gluoncv.py

Note: the UserWarning is fine, because when set target=“llvm” it also has this output but run ok, but the “zsh: abort” info output is very wierd, because i didn’t presss any Ctrl+Z!
