RuntimeError: Cannot find any valid schedule for ["conv2d_layer", 1, 7, 7, 512, 512, 3, 3, [1, 1], [1, 1]] in file conv2d.json

When I use Auto’s routine ‘Auto-scheduling a Convolution Layer for GPU’ I get the following error: RuntimeError: Cannot find any valid schedule for [“conv2d_layer”, 1, 7, 7, 512, 512, 3, 3, [1, 1], [1, 1]] in file conv2d.json
