Run LSTM with NCS2

Hello!

I'm working in Ubuntu and using Python API

I'm trying to run LSTM model in Neural Compute Stick 2.

This is my model summary(model is nonfrozen): 

Model: "model_2"

_________________________________________________________________

Layer (type)        Output Shape        Param #

=================================================================

input_1 (InputLayer)        (None, 5, 2048)        0

_________________________________________________________________

lstm_1 (LSTM)        (None, 256)        2360320

_________________________________________________________________

dense_1 (Dense)        (None, 2)        514

=================================================================

Total params: 2,360,834

Trainable params: 2,360,834

Non-trainable params: 0

When i make model optimization I have success 

sudo python3 mo_tf.py  --input_meta_graph /home/vladislav/tf_model_rnn_2019.09.10/rnn_model.meta --data_type FP16 --output dense_1/Softmax --output_dir /home/vladislav/MIRIAD/ANOTHER/ --input input_1 --input_shape [1,5,2048]

[ SUCCESS ] Generated IR model.
[ SUCCESS ] XML file: /home/vladislav/MIRIAD/ANOTHER/rnn_model.xml
[ SUCCESS ] BIN file: /home/vladislav/MIRIAD/ANOTHER/rnn_model.bin
[ SUCCESS ] Total execution time: 2.89 seconds. 

Then i'm working with Python API

from openvino.inference_engine import IECore, IEPlugin, IENetwork

path_to_xml_file_rnn = '/home/vladislav/MIRIAD/ANOTHER/rnn_model.xml'
path_to_bin_file_rnn = '/home/vladislav/MIRIAD/ANOTHER/rnn_model.bin'

plugin = IEPlugin(device='MYRIAD') 

net_rnn = IENetwork(model=path_to_xml_file_rnn, weights=path_to_bin_file_rnn)
exec_net_rnn = plugin.load(network = net_rnn)

i have this error in last line:

RuntimeError Traceback (most recent call last)

<ipython-input-74-843eb4157227> in <module>

   5 #rnn

   6 net_rnn = IENetwork(model=path_to_xml_file_rnn, weights=path_to_bin_file_rnn)

   ----> 7 exec_net_rnn = plugin.load(network = net_rnn)

ie_api.pyx in openvino.inference_engine.ie_api.IEPlugin.load()

ie_api.pyx in openvino.inference_engine.ie_api.IEPlugin.load()

RuntimeError: AssertionFailed: !ieDims.empty()

How i can solve this problem?

Thank You!

Dear klekovkin, vladislav,

That does look like a very simple LSTM model. Without digging deeper (possible if you attach your model as a *.zip to this ticket) it's hard to say what went wrong.

One question - are you using the latest and greatest OpenVino 2019R2.01 ? If not, can you install it and try again ?

Thanks,

Shubha

Thank you for the answer. I have reinstalled openVINO and have same problem now. I'm attaching keras model to post

Dear klekovkin, vladislav,

I have reproduced this error. I have submitted a bug on your behalf. I will let you know the results as soon as I learn of them. Thanks for your cooperation !

Hello,

I meet a similar error.I use mo.py convert ssd_mobilenet_v2_coco_2018_03_29  tensorflow model to ir model.

Then i write a simple py file with the ir model. The error is same with "RuntimeError: AssertionFailed: !ieDims.empty()".

Soft version is linux:ubuntu 16,openvino:R2.01.

Please give some suggestion for this question,thxs.

Same problem here with Myriad and LSTM

 failed: Failed to compile layer lstm/while/LoopCond/TensorIteratorCondition_/TensorIterator : AssertionFailed: !ieDims.empty()
