【问题描述】：
让 tf.test.is_gpu_available() 返回 True 我缺少什么？ 是否有某种配置文件需要更新？
我使用的是 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：
tabulate 0.8.3
tb-nightly 1.14.0a20190301
tensorboard 1.13.1
tensorflow-datasets 1.0.1
tensorflow-estimator 1.13.0
tensorflow-gpu 2.0.0a0
tensorflow-metadata 0.13.0
termcolor 1.1.0
terminado 0.8.1
terminaltables 3.1.0
testpath 0.4.2
tf-estimator-nightly 1.14.0.dev2019030115
tqdm 4.31.1
traitlets 4.3.2
urllib3 1.24.1
virtualenv 16.0.0
执行：import tensorflow as tf
返回：未找到带有堆栈回溯的 DLL 模型：
