Include the entire stack trace above this error message when asking for help.有人说是因为python版本和tensorflow版本不匹配要么降低python版本要么降低tensorflow版本。如果不是python版本和tensorflow版本不匹配比如我的当前环境为python3.6.5安装tensorflow的版本为2.2win10 64位pip 20.0版本完全匹配呀~ 那是为什么呢如果你前面配置的是CPU版可能是缺少类库MSVCP140.DLL。那么在这个地址https://www.microsoft.com/en-us/download/details.aspx?id53587下载安装即可。这样就能搞定CPU版的tensorflow。三、搞定tensorflow GPU版的问题如果你安装的是GPU版那么接着安装cuda和cudnn正常next就可以了只需要注意环境变量path配一下把cudnn的文件复制到cuda的目录里就OK了。但是tensorflow对cuda和cudnn的版本也有要求。tensorflow2.2通过官网了解只能对应装10.1版本的cuda10.0的还不行。然后再找10.1cuda对应的cudnn7.6.5。这个显卡加速库就算是安装成功了。但如果报驱动和运行版本不对应的错误CUDA driver version is insufficient for CUDA runtime versionailed.可能需要卸载工具包再安装对应的版本。pip uninstall cudnn pip uninstall cudatoolkit但在卸载前要先用pip list 命令看看有没有这些东东。如果没有你可以尝试更新显卡驱动到英伟达官网https://www.nvidia.cn/Download/index.aspx?langcn选择对应的显卡型号更新即可。比如我的显卡是老掉渣的GTX1060最后显示一切OK。I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library cudart64_101.dll I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library nvcuda.dll I tensorflow/core/common_runtime/gpu/gpu_device.cc:1561] Found device 0 with properties: pciBusID: 0000:01:00.0 name: GeForce GTX 1060 computeCapability: 6.1 coreClock: 1.6705GHz coreCount: 10 deviceMemorySize: 6.00GiB deviceMemoryBandwidth: 178.99GiB/s I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library cudart64_101.dll I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library cublas64_10.dll I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library cufft64_10.dll I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library curand64_10.dll I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library cusolver64_10.dll I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library cusparse64_10.dll I tensorflow/stream_executor/platform/default/dso_loader.cc:44] Successfully opened dynamic library cudnn64_7.dll I tensorflow/core/common_runtime/gpu/gpu_device.cc:1703] Adding visible gpu devices: 0 I tensorflow/core/platform/cpu_feature_guard.cc:143] Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 I tensorflow/compiler/xla/service/service.cc:168] XLA service 0x22345614f70 initialized for platform Host (this does not guarantee that XLA will be used).
