save as pb

[zhenglongjiepheonix]

hey, i am using model.save as you mentioned so that i could get .pb file, but it turns out that i only get a file without any suffixes which is not in pb format

according to the official documents, it could only be saved as h5 or tf format, how it could be saved as pb format

Hey, I faced the same error when I tried to create the pb file in Google Colab instead of my AWS environment, however it works just fine in my AWS environment. I'm still trying to figure it out. I'll let you know once it's sorted out. In the meantime, if you figure it out, please let me know. Thanks for pointing it out!

I even tried to convert h5 to pb but when I use model.save() to save the file as "model.h5" , and later try to load using load_model("model.h5"), some error occurs. I think it would be better to implement in TF 1.x framework instead of using high level API like keras, since TF 1.x seems to support pb file better

After all pb file is more important for deployment and acceleration

I think to load the model without using Keras, use tf.saved_model.load('model_directory'). It worked fine for me when I loaded my saved pb model.

Hai when i train the model i got the error
