完全错误：
UnknownError：无法获取卷积算法。这可能是 由于cuDNN无法初始化，因此请尝试查看是否有警告 日志消息已打印在上方。 [Op：Conv2D]
用于软件包安装的命令：
conda install -c anaconda keras-gpu
已安装：
我尝试从nvidia网站安装cuda-toolkit，但该问题仍未解决，因此建议与conda命令相关。
一些博客建议安装Visual Studio，但是如果我有spyder IDE，那有什么需要？
代码：
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Convolution2D
from tensorflow.keras.layers import MaxPooling2D
from tensorflow.keras.layers import Flatten
from tensorflow.keras.layers import Dense
classifier = Sequential()
classifier.add(Convolution2D(32, 3, 3, input_shape = (64, 64, 3), activation = 'relu'))
classifier.add(MaxPooling2D(pool_size = (2, 2)))
classifier.add(Convolution2D(32, 3, 3, activation = 'relu'))
classifier.add(MaxPooling2D(pool_size = (2, 2)))
classifier.add(Flatten())
classifier.add(Dense(units = 128, activation = 'relu'))
classifier.add(Dense(units = 1, activation = 'sigmoid'))
classifier.compile(optimizer = 'adam', loss = 'binary_crossentropy', metrics = ['accuracy'])
from tensorflow.keras.preprocessing.image import ImageDataGenerator
train_datagen = ImageDataGenerator(rescale = 1./255,
shear_range = 0.2,
zoom_range = 0.2,
horizontal_flip = True)
test_datagen = ImageDataGenerator(rescale = 1./255)
training_set = train_datagen.flow_from_directory('dataset/training_set',
target_size = (64, 64),
batch_size = 4,
class_mode = 'binary')
test_set = test_datagen.flow_from_directory('dataset/test_set',
target_size = (64, 64),
batch_size = 4,
class_mode = 'binary')
classifier.fit_generator(training_set,
steps_per_epoch = 8000,
epochs = 25,
validation_data = test_set,
validation_steps = 2000)
执行下面的代码后，我得到了错误消息：
classifier.fit_generator(training_set,
steps_per_epoch = 8000,
epochs = 25,
validation_data = test_set,
validation_steps = 2000)

该错误来自以下事实：
在下面的答案中，我提供了张量流，cuda和cudnn的有效组合。请查看与您的问题类似的问题：Tensorflow 2.0 can't use GPU, something wrong in cuDNN? :Failed to get convolution algorithm. This is probably because cuDNN failed to initialize
例如。 Cuda 10.0 + CuDNN 7.6.3 + / TensorFlow 1.13 / 1.14 / TensorFlow 2.0。
Eg2 Cuda 9 + CuDNN 7.0.5 + TensorFlow 1.10有效
