解決import tensorflow as tf 出錯的原因

筆者在執行 import tensorflow as tf時出現下面的錯誤,但在執行import tensorflow時沒有出錯。

>>> import tensorflow as tf
RuntimeError: module compiled against API version 0xc but this version of numpy is 0xa
ImportError: numpy.core.multiarray failed to import
ImportError: numpy.core.umath failed to import
ImportError: numpy.core.umath failed to import
2018-12-09 01:22:17.925262: F tensorflow/python/lib/core/bfloat16.cc:675] Check failed: PyBfloat16_Type.tp_base != nullp

後執行keras初級教程上的以下程式碼也報錯:

# univariate lstm example
from numpy import array
from keras.models import Sequential
from keras.layers import LSTM
from keras.layers import Dense
# define dataset
X = array([[10,20,30],[20,30,40],[30,40,50],[40,50,60]])
y = array([40,60,70])
# reshape from [samples,timesteps] into [samples,timesteps,features]
X = X.reshape((X.shape[0],X.shape[1],1))
# define model
model = Sequential()
model.add(LSTM(50,activation='relu',input_shape=(3,1)))
model.add(Dense(1))
model.compile(optimizer='adam',loss='mse')
# fit model
model.fit(X,y,epochs=1000,verbose=0)
# demonstrate prediction
x_input = array([50,70])
x_input = x_input.reshape((1,3,1))
yhat = model.predict(x_input,verbose=0)
print(yhat)


經查閱資料後,安裝以下網站的pip install tf-nightly

https://pypi.org/project/tf-nightly/

安裝完成後執行上面所有程式碼就OK了,特此分享!
