Tensorflow GPU错误“您的CPU支持指令…等”[重复]

Question

刚刚安装了Cuda，使用我的GPU获取Tensorflow。我按照上面的说明做了https://www.tensorflow.org/install/gpu并在上运行了Cuda测试https://docs.nvidia.com/cuda/cuda-installathtml" target="_blank">ion-guide-microsoft-windows/（deviceQuery和bandwidthTest）这两个测试都很好。

当我打开PyCharm并运行以下代码时

import tensorflow as tf

print(tf.test.is_gpu_available(
    cuda_only=False,
    min_cuda_compute_capability=None
))

它的计算结果为True，但出现以下错误消息：

这些意味着什么？我应该担心什么？

说明：运行Windows 10，Python 3.6.8，Cuda Toolkit 10.0，Tensorflow 1.13.1

这些不是错误消息，而是信息性消息。以下日期和时间由I指示。这些情况正常发生，无需担心。可以在这里找到不同类型的日志级别。
