Describe the problem

I was trying to load my compiled PyTorch model on my Raspberry 3 by following the following:

https://aws.amazon.com/blogs/aws/amazon-sagemaker-neo-train-your-machine-learning-models-once-run-them-anywhere/

I tried to install the DLR using this script running in a pyenv virtualenv with Python 3.4.10:

https://github.com/neo-ai/neo-ai-dlr/tree/master/install/dlr-1.0-py2.py3-armv7l

But failed because the egg is no longer available. There is also no easy_install3. So I installed the DLR from:

https://neo-ai-dlr.readthedocs.io/en/latest/install.html

using:

https://s3-us-west-2.amazonaws.com/neo-ai-dlr-release/v1.0/pi-armv7l-raspbian4.14.71-glibc2_24-libstdcpp3_4/dlr-1.0-py2.py3-none-any.whl

for rasp2b.

When running the test-dlr.py in:

https://github.com/neo-ai/neo-ai-dlr/blob/master/install/dlr-1.0-py2.py3-armv7l/test-dlr.py

I encountered the following error

TypeError: init() takes 2 to 4 positional arguments but 5 were given

at the code: "model = DLRModel(model_path, input_shape, output_shape, device)

It doesn't seem to be able to take the input_shape and output_shape variables as arguments.

I have the same issue. Were you able to resolve this?

Edit: It worked without giving input_shape, output_shape as arguments
