Python Tensorflow不'；没有常数（但还有其他的吗？）

我最近在一个新的Python3.6.3安装中安装了Tensorflow和

pip

以下代码：

import tensorflow as tf

msgconst = tf.Constant("henlo wrlod lol <4")
thesession = tf.Session()
print(thesession.run(msgconst))
thesession.close()

给予

True

此问题在卸载和重新安装Tensorflow后仍然存在；下面是pip在安装时打印的内容

有什么建议吗？

你可能不想听到这个，但它是

tf.constant(

不是

（请注意，第一个未大写。）

我只是在我的环境中玩弄了一下你的代码才注意到这一点，所以我可以说我确实在使用你的代码时遇到了问题，但是当使用一个小的case

常量时它就起作用了。奇怪的PyCharm建议在
tf.Constant
之前使用
tf.Constant
。。。在顶级模块中有两件东西只随大写字母变化，这是谁的好主意？不知道是谁的主意。很高兴我能帮上忙，我希望这能为你节省一点时间！（友好的编程可能会遇到一个有用的错误，比如“没有张量流常数……你是说常数吗？”）
