Incomplete documentation for tune_relay_arm

#1

Hi,

The documentation at tune_relay_arm mentions the use of use_spatial_pack_depthwise. However, the tune_tasks function doesn’t have such an option/code in the page mentioned.

I did come across the following function which has been mentioned in very old dated posts which mention the following code :

if spatial_pack:
    for i in range(len(tasks)):
        if tasks[i].name == 'topi_nn_depthwise_conv2d_nchw':
            tsk = autotvm.task.create(tasks[i].name, tasks[i].args,
                                      tasks[i].target, tasks[i].target_host,
                                      'contrib_spatial_pack')
            tasks[i] = tsk

Is the tutorial not up to date or has the use of use_spatial_pack_depthwise been deprecated. Either way could someone please point out the best way to autotune a mobilenet architecture for a Raspberry Pi 3B +. Any help would be much appreciated.

Thanks
