Question

我缺少让tf.test.is_gpu_available（）返回True的东西吗？是否有需要更新的配置文件？

我正在使用Python 3.7。{1,2}

之后：pip install --user tensorflow-gpu==2.0.0-alpha0 （之前：pip install --user tensorflow==2.0.0-alpha0）

部分点子列表：

我缺少让tf.test.is_gpu_available（）返回True的东西吗？是否有需要更新的配置文件？

Answer 1

我遇到了类似的问题，对我来说，解决方案是按照下表将CUDA版本与Tensorflow版本进行匹配。（即Tensorflow 1.14需要cuda 10.0）

https://www.tensorflow.org/install/source#linux

Tensorflow命令tf.test.is_gpu_available（）返回False
