NameError: name 'tf' is not defined

[krasserm]

I got it running by defining

def LRN2D(x):
    import tensorflow as tf
    return tf.nn.lrn(x, alpha=1e-4, beta=0.75)

in utils.py i.e. did the tf import inside the function. That's a workaround but I hope it's fine for you.

[krasserm]

That's not an error but only a warning that the model was not compiled. If you only use the (converted) model for prediction you can ignore the warning.

[krasserm]

Yes

[Sparker0i]

Thanks, I did manage to avert that error, but I have got a new one up. I don't know if this is something you could help me with.

Were you able to convert the .h5 into .tflite?

[krasserm]

I tried tflite_convert --output_file test.tflite --keras_model_file test.h5 and it worked i.e. created the output file.

[Sparker0i]

Okay, I did get a .tflite file in the end, but did you encounter an error like this during the process:

WARNING:tensorflow:No training configuration found in save file: the model was *not* compiled. Compile it manually.

[Sparker0i]

Oh ok. Did you encounter that?

[krasserm]

Any objections to close this ticket?
