如何配置支持 CPU 的 tensorflow?
How to configure tensorflow with CPU support?
我正在尝试 运行 tensorflow CPU 支持。
张量流:
版本:1.14.0
凯拉斯:
版本:2.3.1
当我尝试 运行 以下代码时:
def run_test_harness(trainX,trainY,testX,testY):
datagen=ImageDataGenerator(rescale=1.0/255.0)
train_it = datagen.flow(trainX, trainY, batch_size=1)
test_it = datagen.flow(testX, testY, batch_size=1)
model=define_model()
history = model.fit_generator(train_it, steps_per_epoch=len(train_it),
validation_data=test_it, validation_steps=len(test_it), epochs=1, verbose=0)
我收到以下错误,如图所示:

我尝试为相同的配置 bazel,但没有用。如果有人可以指导我获取资源或帮助解决问题,那将会很有帮助。谢谢

您应该尝试 运行在 google colab 上使用您的代码。我认为您的 PC 上没有足够的可用资源来完成您尝试 运行 的任务,即使您使用的 batch_size 为 1.
