I have the same problem.

If you solve this problem,could you share it with me ?

Hey Were you able to solve it? I'm running the hello_ncs_py code

I had the same problem usig ncsdk2 with movidus NCS 1 for the ncappzoo example code video_face_matcher.

The solution for me was commenting out the line the line 8

#import mvnc_simple_api as mvnc

and uncommenting the line 9

from mvnc import mvncapi as mvnc

Hi,

I am also getting the NOT_ALLOCATED problem.

Here is my experiment.

I created the XML and BIN files using the openvino_2019.1.144.

With the XML I created the Movidius specific graph file as below:

/opt/intel/openvino_2019.1.144/deployment_tools/inference_engine/lib/intel64/myriad_compile   -m model/FP16/serialized.xml   -o graph_file_for_tm_npu   -VPU_PLATFORM VPU_2480   -VPU_NUMBER_OF_SHAVES 4   -VPU_NUMBER_OF_CMX_SLICES 4

Now for the generated graph_file_for_tm_npu file, I am trying to import the graph using the following code:

"""NCAPI v2"""
 
### initialization
# from mvnc import mvncapi
# import mvnc.mvncapi as fx
from mvnc import mvncapi as mvnc
 
 
########################  Device Initialization  #######################
device_list = mvnc.enumerate_devices()
device = mvnc.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 = mvnc.Graph('model/graph/graph_file_for_tm_npu')
 
print("able to read the graph successfully .... !")
 
input_descs = graph.get_option(mvnc.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:

---------------------------------------------------------------------------

    691 
    692             # Create an appropriately sized buffer for getting the TensorDescriptor data
 
Exception: Status.NOT_ALLOCATED

Please let me know how to resolve this problem.

Thanks

Kind Regards
