運行DL的TensorBoard示例后出現錯誤
這是示例代碼：
import keras
from keras import layers
from keras.datasets import imdb
from keras.preprocessing import sequence
max_features = 2000
max_len = 500
(x_train, y_train), (x_test, y_test) = imdb.load_data(num_words=max_features)
x_train = sequence.pad_sequences(x_train, maxlen=max_len)
x_test = sequence.pad_sequences(x_test, maxlen=max_len)
model = keras.models.Sequential()
model.add(layers.Embedding(max_features, 128,
input_length=max_len,
name='embed'))
model.add(layers.Conv1D(32, 7, activation='relu'))
model.add(layers.MaxPooling1D(5))
model.add(layers.Conv1D(32, 7, activation='relu'))
model.add(layers.GlobalMaxPooling1D())
model.add(layers.Dense(1))
model.summary()
model.compile(optimizer='rmsprop',
loss='binary_crossentropy',
metrics=['acc'])
callbacks = [
keras.callbacks.TensorBoard(
log_dir='my_log_dir',
histogram_freq=1,
embeddings_freq=1,
# embeddings_data=https://bbs.csdn.net/topics/x_train.astype(float)
)
]
history = model.fit(x_train, y_train,
epochs=20,
batch_size=128,
validation_split=0.2,
callbacks=callbacks)
# tensorboard --logdir=my_log_dir
這是運行錯誤:
Using TensorFlow backend.

@K.eager
AttributeError: module 'keras.backend' has no attribute 'eager'
1.我在網上看了一些解決方法，比較多的是Keras和Tensorflow的版本不統一，我就將其都更新為最新版，Keras-2.3.1及Tensorflow2.1.0，但是問題還是沒有解決。
2.D:\Program Files\Anaconda3\Lib\site-packages\keras\backend\__init__.py中已經有
from .load_backend import eager
我就不清楚是什么原因了
