我正在尝试在计算机上运行NVidia’s face generating demo.我正在使用windows10.我已经下载了源代码,并试图按照页面下方的步骤进行 *** 作.我已经为我的GTX1060安装了最新的NVIDia驱动程序,该驱动程序应该是支持cuda功能的设备.我已经安装了Cuda Toolkit和TensorFlow所需的cuDNN SDK.
但是,运行import_example.py脚本时,出现以下错误.谁能告诉我我在做什么错?

最佳答案Cannot assign a device for operation
G_paper_1/Run/G_paper_1/latents_in: {{node
G_paper_1/Run/G_paper_1/latents_in}}was explicitly assigned to
/device:GPU:0 but available devices are [
/job:localhost/replica:0/task:0/device:cpu:0 ]
您是否安装了tensorflow或tensorflow-gpu?如果要使用GPU,则后者是您想要的.
这也可能是版本兼容性问题.
首先,检查是否安装了nvIDia驱动程序:nvIDia-smi,您应该得到类似以下的内容:
Mon Apr 1 12:30:02 2019 +------------------------------------------------------+ | NVIDIA-SMI 3.295.41 Driver Version: 295.41 | |-------------------------------+----------------------+----------------------+| Nb. name | Bus ID disp. | Volatile ECC SB / DB || Fan Temp Power Usage /Cap | Memory Usage | GPU Util. Compute M. ||===============================+======================+======================|| 0. GeForce GTX 580 | 0000:25:00.0 N/A | N/A N/A || 54% 70 C N/A N/A / N/A | 25% 383MB / 1535MB | N/A Default ||-------------------------------+----------------------+----------------------|| Compute processes: GPU Memory || GPU PID Process name Usage ||=============================================================================|| 0. Not Supported |+-----------------------------------------------------------------------------+
之后,使用nvcc –version检查您拥有的cuda版本.例:
nvcc: NVIDIA (R) Cuda compiler drivercopyright (c) 2005-2016 NVIDIA CorporationBuilt on Mon_Apr__1_12:34:01_CDT_2016Cuda compilation tools,release 8.0,V8.0.44
最终,检查是否已安装兼容版本的python / tensorflow / cuda.为此,对于大多数人来说,使用table作为参考似乎可行.
安装驱动程序后,不要忘记重启!
