"dense_2/Softmax:0" issue

[PoliNicos]

hi, I simply tried to use the model, you kindly shared. I had this issue while trying to "probabilities = model.predict(image)":
"ValueError: Tensor Tensor("dense_2/Softmax:0", shape=(None, 274), dtype=float32) is not an element of this graph."

I cannot understand how to solve this.
Thankx.
