我已经安装了Theano
框架并在我的机器上启用了CUDA,但是当我在Python控制台中输入"import theano"时,我收到了以下信息:
>>> import theano
Using gpu device 0: GeForce GTX 950 (CNMeM is disabled, CuDNN not available)
现在出现了"CuDNN不可用"的情况,我从Nvidia网站下载了cuDnn
。我还更新了环境中的"path",并在".theanorc.txt"配置文件中添加了"optimizer_including=cudnn"。
然后,我再次尝试,但是失败了,出现以下错误:
>>> import theano
Using gpu device 0: GeForce GTX 950 (CNMeM is disabled, CuDNN not available)

有人能帮助我吗?谢谢。
