python - 将 tensorflow 导入 Keras skript 时出现 LinAlgError ("SVD did not converge")

Question

导入tensorflow时出现以下错误:

Intel MKL ERROR: Parameter 4 was incorrect on entry to DLASCL.

使用通用脚本，您也可以将其用于测试:

import tensorflow as tf
from keras.models import Model
from keras.layers import Input
from keras.layers import Dense
from keras.layers import LSTM
from keras.layers.merge import Concatenate
import numpy as np    


# Length of sequence.
sequence_length = 300
# Number of base features 
num_features = 15
# Number of events 
num_event_features = 20

# Input 
input1 = Input(shape=(sequence_length, num_features))
# Build first LSTM on the first input.
h1 = LSTM(50)(input1)

# Apply the dense layer for prediction.
prediction = Dense(1)(h1)

# Define the keras model.
model = Model(inputs=[input1], outputs=[prediction])
model.compile(loss='binary_crossentropy', optimizer='adam',
              metrics=['accuracy'])

# Generate some random data for testing.
X1 = np.random.rand(1000, sequence_length, num_features).astype(np.float32)    
Y = np.random.choice([0, 1], size=1000).astype(np.float32)

# Train the model on random data.
model.fit(x=[X1], y=Y)

如果我删除 import tensorflow as tf，网络将被训练而不会出现错误消息。我正在使用 Keras 2.0.8、python 3.6 和tensorflow 1.3.0。安装 Tensorflow 是为了支持 Ubuntu、python 3.6 和 GPU。

安装 mkl-service 后我遇到了类似的问题。卸载它为我解决了这个问题。
