i haven't tried it but nothing jumps out of why it wouldn't work

mfe7 commented 2 years ago

I just made a small commit changing some print statements so that the node starts up with python3+noetic

Thanks, but I think there may be still some errors or not... In Ubuntu20.04, the default python is pytho3.8 and the tensorflow I can install only is tensorflow2.x. So there are not placeholder. Even I use "import tensorflow.compat.v1 as tf" there still some errors such as "has no attribute 'contrib' " and : "TypeError: Dimension value must be integer or None or have an index method, got TensorShape([Dimension(None), Dimension(256)])" I don't know where I make mistake with your code.

Oh I see. I'm running Python 3.6.9 here rather than the default 3.8 that comes with ubuntu. And I haven't sent commands to the robot that would cause the NN to be queried. I'm not sure I'll have time to get it working with tensorflow2.x -- so one possible path forward would be to run this node in a virtualenv with an older python version that supports tf1 (I have enjoyed using pyenv to manage python versions). I'll post any updates here if I get a chance to update the compatibility.
