Error in importing nengo-loihi1.0.0 on new environment of INRC cloud

Hi, I am working on building ResNet for Loihi with nengo-dl and nengo-loihi.
INRC have upgraded the OS support to Ubuntu 20.04 and Python support to 3.8.x for NxSDK1.0.0.
So, I created a new virtual environment for NxSDK1.0.0 on INRC cloud and installed NxSDK 1.0.0, nengo-dl, and nengo-loihi1.0.0 on INRC Cloud referring Installation — NengoLoihi 1.1.0.dev0 docs.
And then, I tested that those packages installed correctly. Unfortunately, I could not import only nengo-loihi.
I had no problem with the old environment, Ubunts 16.x, python3.6.12, NxSDK0.9.9, nengo3.1.0, nengo-dl 3.4.0 and nengo-loihi0.11.0 on INRC cloud.

I attached error messages and installed package list.
How can I resolve this situation?

Thank you for your cooperation.

Kazuhisa Fujimoto.

Hi @kfujimoto, and welcome to the Nengo forums. :smiley:

The most recent release of NengoLoihi does not yet support NxSDK 1.0.0. In order to use NengoLoihi with NxSDK 1.0.0 support, you’ll need to check out a development version of NengoLoihi:

In your Python environment, do:

git clone https://github.com/nengo/nengo-loihi/
cd nengo-loihi
git checkout nxsdk100
pip install -e .

It is advisable you create a new python environment to make this installation change, just to ensure that any files from the old NengoLoihi install do not interfere with the updated installation.

Note, when I test the environment, I got these warnings:

>>> import nengo_loihi
/homes/xchoo/git/nxsdk-1.0.0/nxsdk/compiler/microcodegen/ProductSeries.py:64: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if const is not 0:
/homes/xchoo/git/nxsdk-1.0.0/nxsdk/compiler/microcodegen/Operations.py:260: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  elif p.numFactors == 0 and p.destination is not 'w':
/homes/xchoo/git/nxsdk-1.0.0/nxsdk/compiler/microcodegen/Operations.py:275: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  elif p.numFactors == 1 and p.destination is not 'w':
/homes/xchoo/git/nxsdk-1.0.0/nxsdk/compiler/microcodegen/Operations.py:348: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if p.numFactors == 1 and p.destination is not 'w':

These seem to originate within the NxSDK code, so you’ll have to message Intel about that.

Hi @xchoo,

Thank you for your reply.
I installed nengo-loihi1.1.0.dev0 in a new conda environment, but unfortunately had the same error in importing nengo_loihi.
I attach the error messages and installed package list.
How should I do?

Thank you for your cooperation.
Kazuhisa Fujimoto.

If you look at the error messages closely, there are two sets of messages.

This set:

2021-05-18 23:23:01.279143: W tensorflow/stream_executor/platform/default/dso_loader.cc:64] Could not load dynamic library 'libcudart.so.11.0'; dlerror: libcudart.so.11.0: cannot open shared object file: No such file or directory; LD_LIBRARY_PATH: /slurm/intel-archi/lib

pertains to TensorFlow being unable to load the GPU drivers necessary to use the GPU with TensorFlow networks. These are just warning messages and are unrelated to the NengoLoihi installation.

The other error (which has been rectified) was this:

With your current environment, you should be able to use NengoLoihi without any issue, assuming you are not expecting to do any TensorFlow training using a GPU.

Thank you for your reply, @xchoo.
I could import nengo-loihi in running my code.
However, I had an another error.

“NotImplementedError: nengo-loihi only supports convolution with ‘valid’ padding”

I build ResNet on SNN and my code is based on CIFAR-10 convolutional network — NengoLoihi 1.1.0.dev0 docs.
This may be the same error as that my colleague hkamei had encountered.
Please check the reply from Eric on Conv2D with ‘same’ padding with Nengo Loihi - Backends / Loihi - Nengo forum

Could you please implement “same” padding for nengo.Convolution in nengo-loihi1.1.0.dev0?

Thank you for your cooperation.

Hi @xchoo and @Eric ,

I tried the sample code “CIFAR-10 convolutional network — NengoLoihi 1.1.0.dev0 docs”, which uses “valid padding” and succesfully worked it with nengoloihi1.0.0dev0 and NxSDK1.0.0 on Loihi in INRC cloud.
So, above mentioned error in my code with “ResNet” must be the same error as that my colleague hkamei had encountered.
Please check the reply from @Eric on Conv2D with ‘same’ padding with Nengo Loihi - Backends / Loihi - Nengo forum.
Could you please resolve this error?
Thank you for your cooperaation.

Hi @kfujimoto,

NengoLoihi was developed in collaboration with Intel and their development of the Loihi platform. Unfortunately, this collaboration ended a few months ago, and because we are a small company, the primary NengoLoihi developer (@Eric) has been prioritized to work on other projects. This means that aside for supporting major NxSDK releases, NengoLoihi is no longer under active development. We may eventually update the same padding code to work with the latest NengoLoihi, but it may take some time for this to happen.
