我正在尝试制作一个卷积神经网络来分析 Microsoft 的猫狗数据集。我在 Windows 10 上使用 tensorflow-gpu 1.12.0、jupyter notebook 和 anaconda。我的 GPU 是 GTX 1080。我安装了 CUDA 和 cuDNN，我很确定我设置正确。我检查了版本。这是我的代码(我把它放在 jupyter 的不同单元格中)。

import tensorflow as tf
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Dense, Dropout, Activation, Flatten, Conv2D, MaxPooling2D
import pickle


import sys
print(sys.executable)
print(tf.__version__)


gpu_options = tf.GPUOptions(per_process_gpu_memory_fraction = 0.4)
session = tf.Session(config=tf.ConfigProto(gpu_options=gpu_options))
print('GPU Settings set')


X = pickle.load(open('X.pickle','rb')) # Brings in the "pictures" of the training set
y = pickle.load(open('y.pickle','rb')) # Brings in the answers


X = X/255.0 # Normalizes the model so each number is between 0 and 1

print('Data Loaded')

model = Sequential()

model.add(Conv2D(64, (3,3), input_shape = X.shape[1:]))
model.add(Activation("relu"))
model.add(MaxPooling2D(pool_size=(2,2)))

model.add(Conv2D(64, (3,3)))
model.add(Activation("relu"))
model.add(MaxPooling2D(pool_size=(2,2)))

model.add(Flatten())
model.add(Dense(64))

model.add(Dense(1))
model.add(Activation('sigmoid'))

model.compile(loss="binary_crossentropy", optimizer='adam', metrics = ['accuracy'])

model.fit(X, y, batch_size=25, epochs=3, validation_split=0.1)

我得到这个错误:

Train on 22451 samples, validate on 2495 samples

最佳答案

希望这 link可以解决你的问题，是因为你安装的cnDNN版本和tensorflow编译出来的cuDNN版本不兼容。

复制一个新的 CUDNN 库，它应该可以工作
