【问题描述】：
我刚刚在新笔记本电脑上安装了 tensorflow。
（Anaconda 4.3.24，Python 3.6.1，TensorFlow：1.2.1，GPU：NVIDIA 1060 6GB）
目前有四个问题。
{1} Spyder 中出现“无法加载本机 TensorFlow 运行时”错误
File "D:/Programs/Codes-Python/OpenCVtest.py", line 13, in <module>
import tensorflow as tf
File "D:\Programs\Anaconda\lib\site-packages\tensorflow\__init__.py", line 24, in <module>

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.
{2} ...但是从命令提示符加载张量流没有（很多）问题
令人困惑的是，当我通过 anaconda prompt 加载 tensorflow -> activate tensorflow -> python -> import tensorflow: 然后导入 tensorflow 时没有错误。
怎么会？如果仅为特定环境安装 tensorflow 库，则 Spyder 中的错误消息应为“No Module Named TensorFlow”....
{3}运行示例时的一些差异
现在当我在 anaconda 提示符下运行测试代码时：
>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
我收到以下“错误”？

但我仍然可以运行测试“print(sess.run(hello))”的最后一部分并得到以下结果。
>>> print(sess.run(hello))
b'Hello, TensorFlow!'
Hello 前面的“b”不应该存在，但在我运行代码时始终存在。为什么？
{4}没有已知的设备错误 - GPU 无法识别？ 最后，当我检查正在使用的设备时，tensorflow 似乎无法识别 GPU。为什么？我试过分别卸载、重新安装 tensorflow 和 tensorflow-GPU 无济于事。
>>> sess = tf.Session(config = tf.ConfigProto(log_device_placement=True))
Device mapping: no known devices.

任何帮助将不胜感激。 谢谢， 中文
