私はケラスを使用しており、テンソルボードを使用してログをプロットしようとしています。私が得ているエラーと、私が使用しているパッケージのバージョンのリストを見つけることができます。 'Sequential'オブジェクトに '_get_distribution_strategy'属性がないというエラーが発生していることを理解できません。
パッケージ:Keras 2.3.1 Keras-Applications 1.0.8 Keras-Preprocessing 1.1.0 tensorboard 2.1.0 tensorflow 2.1.0 tensorflow-estimator 2.1.0
モデル:
model = Sequential()
model.add(Embedding(MAX_NB_WORDS, EMBEDDING_DIM, input_shape=(X.shape[1],)))
model.add(GlobalAveragePooling1D())
#model.add(Dense(10, activation='sigmoid'))
model.add(Dense(len(CATEGORIES), activation='softmax'))
model.summary()
#opt = 'adam' # Here we can choose a certain optimizer for our model
opt = 'rmsprop'
model.compile(loss='categorical_crossentropy', optimizer=opt, metrics=['accuracy']) # Here we choose the loss function, input our optimizer choice, and set our metrics.
# Create a TensorBoard instance with the path to the logs directory
tensorboard = TensorBoard(log_dir='logs/{}'.format(time()),
histogram_freq = 1,
embeddings_freq = 1,
embeddings_data = X)
history = model.fit(X, Y, epochs=epochs, batch_size=batch_size, validation_split=0.1, callbacks=[tensorboard])

あなたのpython環境はkeras
とtensorflow.keras
からのインポートを混合しているようです。次のようにSequentialモジュールを使用してみてください:
model = tensorflow.keras.Sequential()
または、インポートを次のように変更します
import tensorflow
layers = tensorflow.keras.layers
BatchNormalization = tensorflow.keras.layers.BatchNormalization
Conv2D = tensorflow.keras.layers.Conv2D
Flatten = tensorflow.keras.layers.Flatten
TensorBoard = tensorflow.keras.callbacks.TensorBoard
ModelCheckpoint = tensorflow.keras.callbacks.ModelCheckpoint
...等
