Neural Compute SDK version 2.04 is now available! The NCAPPZOO has also been updated for NCSDK 2!

What’s new in NCSDK 2.04?

 

Multiple graph allocations on a single NCS device is now possible! This feature allows for users to use multiple graph files from multiple models and queue them up for inference in a sequential manner.

 

NCSDK 1 can still be found on the master branch of the NCSDK repository, although NCSDK 1 will likely be replaced by NCSDK 2 in the near future. At the moment, NCSDK version 2.xx will be on the ncsdk2 branch of the github repo. To install NCSDK version 2.xx, you can use the following command:

 

git clone -b ncsdk2 https://github.com/movidius/ncsdk.git

 

More details and information on the differences between NCSDK 1 and NCSDK 2 can be found at https://movidius.github.io/ncsdk/ncapi/readme.html. Additionally NCSDK version 2.04.00.06 release notes can be found at https://movidius.github.io/ncsdk/release_notes.html.

 

The NCAPPZOO has also been updated for NCSDK 2!

 

To view the NCAPPZOO examples for NCSDK 2, please visit https://github.com/movidius/ncappzoo/ and switch to the ncsdk2 branch of the repository. The NCSDK v 1.12 version of the NCAPPZOO will stay in the master branch of the NCAPPZOO.

@Tome_at_Intel , does Neural Compute SDK version 2.04 support 16 bit floating point?

 

I tried to generate graph by mvNCCompile tool from tensorflow model(.pb, file which is 32bit), and I did not find the there is a parameter which could specify 16bit or 32bit floating point. And the output graph works well. And before I used same .pb file to generate graph by NCSDK 1.2, the output is 16bit floating point, and it works as well.

 

So my question is whether 2.04 still supports 16bit float point, maybe according to the input model(.pb) or with specific parameter? Or it only supports 32bit floating point now?

 

Thanks for your answer in advance.

@minnowspirit Yes the NCSDK does support fp16. But now it takes fp32 and does the conversion internally now. You can read more about it at https://movidius.github.io/ncsdk/ncapi/python_api_migration.html. Scroll down to the input/output data types section.

I have install the NCSDK 1. , how could I upgrade to the NCSDK 2. I use the uninstall commant to uninstall the NCSDK1 and then install the NCSDK2. But I meet error and I don't know how to fix it. Could you pls give a help .Thanks!@Tome_at_Intel

I do not know if it will work or not.

 

Various packages seem to be old.

@shartoo

 

I do not know if it will be helpful, but it is the repository I created.

 

I am implementing Multi Graph.

 

Load two or three graphs simultaneously.

 

Because it is logic based on Multi Stick, the part of "Try ~ Except ~" may be a bit confusing.

 

https://github.com/PINTO0309/MobileNet-SSD-RealSense.git

 

MultiStickSSDwithRealSense.py

 

# 1:= Enabled MobileNet-SSD Model if ssd_detection_mode == 1: with open(join(graph_folder, "graph"), mode="rb") as f: graph_buffers.append(f.read()) graphs.append(mvnc.Graph('MobileNet-SSD')) # 1:= Enabled Fullweight FaceDetection Model if face_detection_mode == 1: with open(join(graph_folder, "graph.fullfacedetection"), mode="rb") as f: graph_buffers.append(f.read()) graphs.append(mvnc.Graph('FullFaceDetection')) # 2:= Enabled Lightweight FaceDetection Model if face_detection_mode == 2: with open(join(graph_folder, "graph.shortfacedetection"), mode="rb") as f: graph_buffers.append(f.read()) graphs.append(mvnc.Graph('ShortFaceDetection')) devopen = False for device in devices: try: device = mvnc.Device(device) device.open() for (graph, graph_buffer) in zip(graphs, graph_buffers): graphHandles.append(graph.allocate_with_fifos(device, graph_buffer)) devopen = True break except: continue

 

By the way, MTCNN has multiple output problems, it is impossible to smartly implement with NCSDK v2.

Hi @PINTO i have tried loading three model of MTCNN's three stage in one stick but failed.Here is what i did:

 

def load_graph(graph_file1,graph_file2,graph_file3): #mvnc.SetGlobalOption(mvnc.GlobalOption.LOG_LEVEL, 0) devices = mvnc2.enumerate_devices() if len(devices) == 0: print('No devices found') return 1 device = mvnc2.Device(devices[0]) device.open() # Load graph from disk and allocate graph via API with open(graph_file1, mode='rb') as f: graph_from_disk1 = f.read() graph1 = mvnc2.Graph("graph1") fifo_in1, fifo_out1 = graph1.allocate_with_fifos(device, graph_from_disk1) with open(graph_file2, mode='rb') as f: graph_from_disk2 = f.read() graph2 = mvnc2.Graph("graph2") fifo_in2, fifo_out2 = graph2.allocate_with_fifos(device, graph_from_disk2) with open(graph_file3, mode='rb') as f: graph_from_disk3 = f.read() graph3 = mvnc2.Graph("graph3") fifo_in3, fifo_out3 = graph3.allocate_with_fifos(device, graph_from_disk3) return graph1,fifo_in1, fifo_out1,graph2,fifo_in2, fifo_out2,graph3,fifo_in3, fifo_out3

It seems that load two graph is ok,while fail when loading a third graph.

There is a caffe version of MTCNN here caffe-mtcnn github,what i did above was cloned the caffe-mtcnn and compiled the caffe model using nvccCompile of ncsdk for using accelerator of ncsdk

Please show below.

 

Unfortunately, Intel's engineers say it is a bug in NCSDK.

 

https://ncsforum.movidius.com/discussion/1259/cant-load-more-than-two-models#latest

 

I think your question is not appropriate for this topic.

 

(Because it is hard to touch the eyes of other expert engineers.)

 

I think it would be better to create a new topic yourself.
