我使用以下命令安装了tensorflow。
pip install tensorflow
我正在运行一个简单的程序
import tensorflow as tf
node1 = tf.constant(3.0, tf.float32)
node2 = tf.constant(4.0) # also tf.float32 implicitly
print(node1, node2)
运行程序时出现以下错误。

此错误消息通常表示在您的系统上找不到TensorFlow的依赖项之一。由于您在Windows上使用仅CPU版本的TensorFlow，最可能缺少的DLL是msvcp140.dll，这是运行使用Microsoft Visual C ++ 2015编译的程序所必需的。此DLL通常安装在开发人员计算机上作为Visual Studio，或者像Anaconda这样的Python发行版。但是，Python for Python的Python.org发行版不包含它。
您可以通过下载并安装Microsoft Visual C++ 2015 Redistributable Update 3。
在您的系统上安装msvcp140.dll
