Freez.py for tensrflow2.5 versin

[Aishaj]

Hi, I'm trying to edit the freez.py from the main project folder( which is Tensorflow 1.X). to make it suitable for thates project files( Tensorflow 2.5) However, when running python freeze.py --model_architecture ds_cnn --model_size_info 5 64 10 4 2 2 64 3 3 1 1 64 3 3 1 1 64 3 3 1 1 64 3 3 1 1 --checkpoint ../Pretrained_models/DS_CNN/DS_CNN_S/ckpt/ds_cnn_0.94_ckpt --output_file ds_cnn.pb

I'm getting the following error

Would appreciate any help regarding this. Thanks

freeze.py in the original repository was for generating a frozen .pb model file for inference. This model format is exclusive to TensorFlow 1 and is not supported in TensorFlow 2.

In this repository you can instead generate a TFLite file using convert.py that will be suitable for deployment. You can pass in --no-quantize to generate a floating point file if you wish so that it matches the .pb model.

The reason of me trying to create the freez.py is because I want to use label_wav.py. So I want to send a sound file to the model. However, label_wav.py requires a .pb file

[Burton2000]

This merge request https://github.com/ARM-software/ML-examples/pull/72 has a new label_wav.py file that should work with tflite files, give it a try and see if it works for you.
