Export to Tensorflow problems

[zlelik]

I am trying to export *.pt model to tensorflow like this
python export.py --weights yolov9-e-converted.pt --include saved_model

and I am getting this error

TensorFlow SavedModel: export failure ❌ 1.7s: cannot import name 'C3' from 'models.common' (/root/conversion/yolov9/models/common.py)

python export.py --weights yolov9-e-converted.pt --include pb
fails with another error

TensorFlow SavedModel: export failure ❌ 5.1s: cannot import name 'C3' from 'models.common' (/root/conversion/yolov9/models/common.py)
TensorFlow GraphDef: starting export with tensorflow 2.18.0...
TensorFlow GraphDef: export failure ❌ 0.0s: 'NoneType' object has no attribute 'inputs'

python export.py --weights yolov9-e-converted.pt --include tfjs
fails with this error

TensorFlow SavedModel: export failure ❌ 1.7s: cannot import name 'C3' from 'models.common' (/root/conversion/yolov9/models/common.py)

TensorFlow GraphDef: starting export with tensorflow 2.18.0...
TensorFlow GraphDef: export failure ❌ 0.0s: 'NoneType' object has no attribute 'inputs'

tensorflow.python.framework.errors_impl.NotFoundError: yolov9-e-converted.pb; No such file or directory
TensorFlow.js: export failure ❌ 4.5s: [Errno 2] No such file or directory: 'yolov9-e-converted_web_model/model.json'

But
python export.py --weights yolov9-e-converted.pt --include onnx
works fine and produces file yolov9-e-converted.onnx file.

I do not need speed or GPU. I just need to convert it and if it takes 2 days to convert, I am fine. I need to do it once.
or maybe I am doing something completely wrong and using export.py in a wrong way?
