Try Anaconda install steps from TensorFlow docs.

小开

I was trying to install tensorflow GPU for a Windows 7 with pip3 for python3.5.x. Instead of doing pip3 install --upgrade tensorflow I just did pip install tensorflow and after it completed i was finally able to import tensorflow in python3.5.x.

小开

Check if Tensorflow was installed successfully using:

 pip3 show tensorflow

If you get something like

Name: tensorflow
Version: 1.2.1
Summary: TensorFlow helps the tensors flow
Home-page: http://tensorflow.org/
Author: Google Inc.
Author-email: opensource@google.com
License: Apache 2.0
Location: /usr/local/lib/python3.5/dist-packages
Requires: bleach, markdown, html5lib, backports.weakref, werkzeug, numpy, protobuf, wheel, six

You may try adding the path of your tensorflow location by:

export PYTHONPATH=/your/tensorflow/path:$PYTHONPATH.

小开

Try installing tensorflow again with the whatever version you want and with option --ignore-installed like:

pip install tensorflow==1.2.0 --ignore-installed

I solved same issue using this command.

小开

Try installing tensorflow in the user site - This installation only works for you.

pip install tensorflow --user

小开

For Anaconda3, simply install in Anaconda Navigator:

小开

Activate the virtualenv environment by issuing one of the following commands:

$ source ~/tensorflow/bin/activate # bash, sh, ksh, or zsh
$ source ~/tensorflow/bin/activate.csh # csh or tcsh

Hope this help

This Worked for me:

$ sudo easy_install pip
$ sudo easy_install --upgrade six
$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/tensorflow-0.9.0-py2-none-any.whl
$ sudo pip install --upgrade $TF_BINARY_URL

I had a more basic problem when I received this error.

The "Validate your installation" instructions say to type: python

However, I have both 2.7 and 3.6 installed. Because I used pip3 to install tensorflow, I needed to type: python3

Using the correct version, I could import the "tensorflow" module.

小开

Instead of using the doc's command (conda create -n tensorflow pip python=2.7 # or python=3.3, etc.) which wanted to install python2.7 in the conda environment, and kept erroring out saying the module can't be found when following the installation validation steps, I used conda create -n tensorflow pip python=3 to make sure python3 was installed in the environment.

Doing this, I only had to type python instead of python3 when validating the installation and the error went away.

小开

You may need this since first one may not work.

python3 -m pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl

小开

with python2

pip show tensorflow to check install

python test.py to run test

with python3

pip3 show tensorflow to check install

python3 test.py to run test

test.py

import tensorflow as tf
import numpy as np


c = np.array([[3.,4], [5.,6], [6.,7]])
step = tf.reduce_mean(c, 1)
with tf.Session() as sess:
print(sess.run(step))

Or, if you haven't install tensorflow yet, try the offical document

小开

you might wanna try this:

$conda install -c conda-forge tensorflow

小开

I had exactly the same problem. It's because default python is in version 2 You need to link to the version 3.

>sudo rm -rf /usr/bin/python
>sudo ln -s /usr/bin/python3.5 /usr/bin/python

小开

I ran into the same issue. I simply updated my command to begin with python3 instead of python and it worked perfectly.

小开

In my case, I install 32 Bit Python so I cannot install Tensorflow, After uninstall 32 Bit Python and install 64 Bit Python, I can install tensorflow successfully.

After reinstall Python 64 bit, you need to check your python install folder path is properly set in Windows Environment Path.

You can check Python version by typing python in cmd.

For me, if I did

python3 -m pip install tensorflow

then I got the error the OP reports when using a 3rd party library calling tensorflow.

However, when I substituted either tensorflow-cpu or tensorflow-gpu (depending upon which one is appropriate for you) then the code was suddenly able to find tensorflow.

小开

On my remote machine, I had TensorFlow installed via pip and when I was importing it in ipython the import was successful. Despite of that I still got the No module named tensorflow error when I was running my scripts. The issue here was that I was running my scripts with sudo, so the python and tensorflow paths were not visible to the root. When I ran my scripts without sudo, everything worked.

小开

My experience.

A, check your python version, in my case python 3.6

B, use the command: python3.6 myscript.py;

C, my tensorflow version is 1.10

小开

It's a bit late answer, but I guess might be a common one. I had encountered the same problem and neither of the proposed methods in here worked for my case, Python v3.7 and working on a Linux server. I tested the following command line and it worked for me:

python3 -m pip install tensorflow

小开

If you remove all underscores in the jupyter notebook file name, it should start working. No idea why.

For example, test.ipynb could import tensorflow, but test_test.ipynb couldn't.

If you're like me, you created a jupyter notebook file (.ipynb) and couldn't import tensorflow even though it installed properly.

This problem didn't occur with normal python files (.py), regardless of whether they had underscores in their names or not.

I'm using vscode if that matters.
