Maximum fifo depth limited to 64?

Allocateing 128 element fifo:

 

fifo = Fifo('test_fifo', FifoType.HOST_WO) fifo_size = 128 fifo.allocate(device, graph.get_option(GraphOption.RO_INPUT_TENSOR_DESCRIPTORS)[0], fifo_size) data = np.empty(shape=(32, 32)).astype(np.float32) for i in range(fifo_size): print(i) fifo.write_elem(data, None)

 

write_elem starts blocking on iteration 64.

 

Is there some hidden limit to fifo sizes?

@gasparka This is unintended and the limit shouldn't be 64. Thanks for reporting this bug. Appreciate your help!
