Unable to run import tensorflow as tf

Question

I installed tensorflow using the following command.

pip install tensorflow

I am running a simple program which is

import tensorflow as tf
node1 = tf.constant(3.0, tf.float32)
node2 = tf.constant(4.0) # also tf.float32 implicitly
print(node1, node2)

I am getting the following error on running the program.

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

for some common reasons and solutions.  Include the entire stack trace above this error message when asking for help.

I have updated the pip and am running the program on python 3.5

Answer 1

This error message typically means that one of TensorFlow's dependencies cannot be found on your system. Since you are using the CPU-only version of TensorFlow on Windows, the most likely missing DLL is msvcp140.dll, which is required to run programs compiled using Microsoft Visual C++ 2015. This DLL is usually installed on developer machines as part of Visual Studio, or some Python distributions like Anaconda. However, the Python.org distribution of Python for Windows does not include it.

You can install msvcp140.dll on your system by downloading and installing the Microsoft Visual C++ 2015 Redistributable Update 3.

For others who find this answer, note that this script can help to diagnose common TensorFlow on Windows installation issues.

Answer 2

I'm not exactly sure what the problem is, and probably as clueless as you about the error message, but as you are using python 3.x, shouldn't you have installed tensorflow by using:

pip3 install tensorflow

To see if you are using pip3 type:

pip3 -V

I hope this helps
