我已经在我的机器上安装了Theano
框架并启用了 CUDA,但是当我在我的 python 控制台中“导入 theano”时,我收到了以下消息:
>>> import theano
Using gpu device 0: GeForce GTX 950 (CNMeM is disabled, CuDNN not available)
现在“CuDNN 不可用”,我cuDnn
从 Nvidia 网站下载。我还更新了环境中的“路径”,并在“.theanorc.txt”配置文件中添加了“optimizer_including=cudnn”。
然后,我再次尝试,但失败了:
>>> import theano
Using gpu device 0: GeForce GTX 950 (CNMeM is disabled, CuDNN not available)
