尝试保存 tensorflow model 时，模块“h5py”没有属性“文件”

Question

So I Just made a small NN with the MNIST Digit Database and I'm trying to save it. Here is the full code:

# Importing Libs
import h5py
import tensorflow as tf
import numpy as np
import matplotlib.pyplot as plt
from tensorflow import keras

# ---------- PART I: Importing and cleaning Data ----------
# Importing Data
train_data = np.genfromtxt('mnist_train.csv', delimiter=',')[1:]
test_data  = np.genfromtxt('mnist_test.csv', delimiter=',')[1:]

train_images = train_data[:, 1:]
train_labels = train_data[:, 0]

test_images  = test_data[:, 1:]
test_labels  = test_data[:, 0]

class_names = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

train_images = train_images/255
test_images = test_images/255

train_images = train_images.reshape(60000, 28, 28)
test_images = test_images.reshape(10000, 28, 28)

# ---------- PART II: Making the model ----------
layers = [keras.layers.Flatten(input_shape=(28, 28)), 
          keras.layers.Dense(128, activation='relu'), 
          keras.layers.Dense(10, activation='softmax')]

model = keras.Sequential(layers)
model.compile(optimizer='adam', 
              loss='sparse_categorical_crossentropy', 
              metrics=['accuracy'])


model.fit(train_images, train_labels, epochs=1
model.save("network.h5")

And here is the traceback:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

    101     # TODO(b/130258301): add utility method for detecting model type.

AttributeError: module 'h5py' has no attribute 'File'

My versions:

1. tensorflow: 2.1.0
2. keras: 2.2.4-tf
3. h5py: 2.10.0
4. Anaconda: 2019.10

Any help would be greatly appreciated.

Answer 1

Try this.Its working fine.

from tensorflow.keras.models import load_model
model.save("model.h5")
print("Saved model to disk")
 
# load model
model = load_model('model.h5')

Answer 2

I solved this problem in my environment downgrading the h5py module to 3.1.0, witch in TensorFlow 2.6 compatible.

Answer 3

Actually, this is a problem with versions of the different libraries. I have also faced the same problem when using TensorFlow. From the anaconda prompt, you can check which version of h5py is compatible with TensorFlow. I have tried uninstalling and reinstalling many times but at last, installing a compatible version of h5py, the problem was solved. Conda prompt screenshot can be checked here .
