Hi ,
I converted my CNN model using mo_tf.py into different input resolutions and tested both with Movidius and Movidius X. When the resolution is large, Movidius X crashed. My model is very small model and the bin file is only around 168K Bytes.
Input Resolutions:
1) 256x256x3
Movidius worked fine, Movidius X worked fine.
2)900x900x3
Movidius worked fine, Movidius X worked fine.
3)1280x1024x3
Movidius worked fine, Movidius X crashed. The error message is shown below.
Thanks.
Xianju

Hi,
I am using the Movidius Graph file using NCAPI.
I am using the following code for reading the graph file:
"""NCAPI v2""" ### initialization from mvnc import mvncapi import mvnc.mvncapi as fx ######################## Device Initialization ####################### device_list = fx.enumerate_devices() device = fx.Device(device_list[0]) ######################################################################## device.open() ####################### Load Neural Network ######################## # Initialize a graph from file at some GRAPH_FILEPATH GRAPH_FILEPATH = 'model/graph/graph_file_for_tm_npu' with open(GRAPH_FILEPATH, mode='rb') as f: graph_buffer = f.read() graph = fx.Graph('model/graph/graph_file_for_tm_npu') print("able to read the graph successfully .... !") input_descs = graph.get_option(fx.GraphOption.RO_INPUT_TENSOR_DESCRIPTORS) print(input_descs) # CONVENIENCE FUNCTION: # Allocate the graph to the device and create input/output Fifos with default options in one call # input_fifo, output_fifo = graph.allocate_with_fifos(device, graph_buffer) ######################################################################## device.close() device.destroy()
But I am getting the following error
--------------------------------------------------------------------------- Exception Traceback (most recent call last) <ipython-input-1-7ff11ca99aa0> in <module> 24 print("able to read the graph successfully .... !") 25 ---> 26 input_descs = graph.get_option(fx.GraphOption.RO_INPUT_TENSOR_DESCRIPTORS) 27 28 print(input_descs) /usr/lib/python3.5/site-packages/mvnc/mvncapi.py in get_option(self, option) 688 self.handle, GraphOption.RO_INPUT_COUNT.value, byref(desc_count), byref(optsize)) 689 if status != Status.OK.value: --> 690 raise Exception(Status(status)) 691 692 # Create an appropriately sized buffer for getting the TensorDescriptor data Exception: Status.NOT_ALLOCATED
Can you please help me knowing what is the problem using NCAPI?
Please help
Kind Regards
Arun
