列出可用GPU from tensorflow.python.client import device_lib print(device_lib.list_local_devices()) from keras import backend as K K.tensorflow_backend._get_available_gpus() 切换 import os os.environ["CUDA_DEVICE_ORDER"]="PCI_BUS_ID" # The GP…
在训练keras时,发现不使用GPU进行计算,而是采用CPU进行计算,导致计算速度很慢. 用如下代码可检测tensorflow的能使用设备情况: from tensorflow.python.client import device_lib print(device_lib.list_local_devices()) 查看是否只有CPU可用,发现不是,有GPU可用,但是为什么GPU利用率极低并且只有一个GPU在使用,另一个GPU利用率为0, 发现在启动时有一行报错: Could not load…
Most processes can be described as either I/O bound or CPU bound. 大多数进程都可以描述为IO绑定或者CPU绑定. An I/O-bound process is one that spends more of its time doing I/O than it spends doing computations. A CPU-bound process, in contrast, generates I/O requests i…
Asynchronous programming has had a lot of attention in the last couple of years and there are two key reasons for this: First it helps in providing a better user experience by not blocking the UI thread which avoids the hanging of the UI screen until…
