在windows10使用tensorflow1.0.0和python3.5的环境下，我的cuda使用的9.0。
在运行：
|
1 |
>>> import tensorflow as tf |
出现以下错误
|
1 2 3 4 |
108] Couldn't open CUDA library cublas64_80.dll 102] Couldn't open CUDA library cudnn64_5.dll 108] Couldn't open CUDA library cufft64_80.dll 108] Couldn't open CUDA library curand64_80.dll |
这是因为tensorflow1.0.0只能支持到80，所以他会找***_80.dll,cudnn64_5.dll,但这些dll都不存在，怎么办呢？
其实很简单：
1.来到CUDA\v9.0\bin
2.复制cublas64_90.dll cudnn64_7.dll cufft64_90.dll curand64_90.dll 将其分别复制成新的 cublas64_80.dll cudnn64_5.dll cufft64_80.dll curand64_80.dll
重启命令行工具
重新输入

>>> import tensorflow as tf |

大功告成！！！！
