Error AssertionFailed: !ieDims.empty() when apply pre-train model (Reinforcement Learning) on NCS2

I have a problem when I try to run my model Reinforcement Learning (RL) with LSTM on VPU (NCS2). It cannot load my network to the device (plugin = IEPlugin(device="MYRIAD")). But if I change device=CPU or GPU, It’ll work well.

 

This is my code I face the issue :

 

from openvino.inference_engine import IENetwork, IEPlugin

plugin = IEPlugin(device="MYRIAD")

net = IENetwork(model=model_xml, weights=model_bin)

exec_net = plugin.load(network=net)

 

This is the error I got :

Traceback (most recent call last):

 File "NCS2_UTL_test.py", line 68, in <module>

  exec_net = plugin.load(network=net)

 File "ie_api.pyx", line 1205, in openvino.inference_engine.ie_api.IEPlugin.load

 File "ie_api.pyx", line 1215, in openvino.inference_engine.ie_api.IEPlugin.load

RuntimeError: AssertionFailed: !ieDims.empty()

 

So, can you give me the reason and how can I fix it if I want to run it on VPU?

Thank you

Hi Andrew,

 

It seems like the layer is not supported by MYRIAD plugin; you can check that here. However, check this thread can be helpful.

Hi Randall B,

I tried to use the thread but it's still not working. You montioned the layer is not supported by MYRIAD, so how can I show exactly what's the name of layer is not supported?

Thanks.

Additionly, This's my error I got when trying to through the xml replacing : 

 

<output>

                <port id="1" precision="I64"/>

</output>

To

 

            <output>

                <port id="1" precision="I64">

                    <dim>1</dim>

                </port>

            </output>

 

 

Traceback (most recent call last):

 File "NCS2_UTL_test.py", line 59, in <module>

  net = IENetwork(model=model_xml, weights=model_bin)

 File "ie_api.pyx", line 980, in openvino.inference_engine.ie_api.IENetwork.__cinit__

RuntimeError: Check 'axis_ps.rank().is_static() && (size_t)axis_ps.rank() == 0' failed at ..\ngraph\src\ngraph\op\fused\split.cpp:133:

While validating node 'Split[Split_148](Reshape_146: float{1,248}, Constant_147: int64_t{1}) -> (??)':

The 'axis' input is expected to be a scalar. Got: {1}

 

This error occurs both running on CPU device and VPU when changing the xml.

And I can still run on the CPU if I don't change the xml file according to your instructions.

 

Thanks

Hi Andrew,

 

Unfortunately, the LSTM is not supported by the MYRIAD plugin (NCS2).

Let me know if you have additional questions.

 

Regards,

Randall B.
