Error when converting Pytorch model to DeepViewRT model

Anonymous123 — Wed, 07 Jun 2023 20:51:46 GMT

Hi community,

I'm seeking your help in solving the following issue ..

I installed eIQ Toolkit 1.7.3 on Windows 10 and I want to convert my Pytorch model to DeepViewRT (.rtm) model, so I can eventually deploy the .rtm model on the i.MX 8M Plus processor.

I followed this guide, I converted the Pytorch model to ONNX model, then as described in the guide, I tried to convert the ONNX model to a quantized ONNX model.

However, the conversion process terminated with an unhelpful error message: "object of type 'NoneType' has no len()".

I used the Model Tool from the eIQ Portal when I did the conversion.

Thanks in advance and best regards.

Hello,

It looks like your model is passed on size, you can download and evaluated the performance with:

Hi @Bio_TICFSL,

Actually, when I changed the batch size when exporting from Pytorch to ONNX to 1, the conversion was done successfully..

However, I encountered this only when converting from ONNX to quantized ONNX, for example, I managed to convert the same model (Pytorch to ONNX to Tensorflow saved model format to quantized Tensorflow Lite) with larger batch sizes.

So how I can get rid of this error, according to the Guide I mentioned, I have to concert the ONNX to a quantized ONNX before converting to RTM, and I can't get rid of this error.

Regards
