модуль 'h5py' не имеет атрибута 'File' при попытке сохранить модель тензорного потока

Question

Итак, я только что создал небольшую сеть с базой данных MNIST Di git и пытаюсь ее сохранить. Вот полный код:

# 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")

А вот трассировка:

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

   1006     """

     97 
     98   if (save_format == 'h5' or
---> 99       (h5py is not None and isinstance(filepath, h5py.File)) or
    100       os.path.splitext(filepath)[1] in _HDF5_EXTENSIONS):
    101     # TODO(b/130258301): add utility method for detecting model type.

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

Мои версии:

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

Любая помощь будет принята с благодарностью.

Попробуйте вот так. Работает нормально.

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