How to find which version of TensorFlow is installed in my system?

Question

I need to find which version of TensorFlow I have installed. I'm using Ubuntu 16.04 Long Term Support.

To retreive the summary (incl. version of package) try: `pip show [package name]`, eg: `pip show tensorflow`, `pip show numpy` etc. — Sumanth Lazarus, Jul 30 '19 at 12:30
Anyone knowing the difference between `tf.__version__` and `tf.version.VERSION`? My 0.12.0 installation doesn't support latter. — Jianyu, Oct 05 '20 at 12:36
relevant TensorFlow 2.x API docs (`tf.version.VERSION` is a v2.0 API): https://www.tensorflow.org/api_docs/python/tf/version — michael, Jan 25 '21 at 00:43

This depends on how you installed TensorFlow. I am going to use the same headings used by TensorFlow's installation instructions to structure this answer.

Pip installation

Run:

python -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 2
python3 -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 3

Note that python is symlinked to /usr/bin/python3 in some Linux distributions, so use python instead of python3 in these cases.

pip list | grep tensorflow for Python 2 or pip3 list | grep tensorflow for Python 3 will also show the version of Tensorflow installed.

Virtualenv installation

Run:

python -c 'import tensorflow as tf; print(tf.__version__)'  # for both Python 2 and Python 3

pip list | grep tensorflow will also show the version of Tensorflow installed.

For example, I have installed TensorFlow 0.9.0 in a virtualenv for Python 3. So, I get:

$ python -c 'import tensorflow as tf; print(tf.__version__)'
0.9.0

$ pip list | grep tensorflow
tensorflow (0.9.0)

and if you are building from source, your version is commit hash from `git rev-parse HEAD` – Yaroslav Bulatov Jul 26 '16 at 04:53

Got ```'module' object has no attribute '__version__'``` when ```python -c 'import tensorflow as tf; print(tf.__version__)'``` – user3768495 Dec 09 '16 at 02:53
@user3768495 Hmm, interesting, let me test that later. Meanwhile, the `pip list` way should work if you used `pip` for installation. – edwinksl Dec 09 '16 at 03:14
```pip list | grep tensorflow``` worked tho. My version is 0.5.0. Maybe it's toooo old to have the '__version__' attribute? – user3768495 Dec 09 '16 at 03:26

@user3768495 If you installed Tensorflow with VirtualEnv you need to activate the environment and that must be done for any new console you open (source ~/tensorflow/bin/activate). Once you do that you can retrieve your tensorflow version (pip list | grep tensorflow) – Nestor Urquiza Mar 18 '18 at 14:29
@Nestor Urquiza do you mean anaconda console under Linux ? – Qbik Nov 19 '18 at 16:10

for Windows CMD you need to use double quote `"` instead of `'`: `python3 -c "import tensorflow as tf; print(tf.__version__)"` – user924 Dec 15 '18 at 19:46
I tried both pip and python, i.e. `pip list | grep tensorflow` and `python -c 'import tensorflow as tf; print(tf.__version__)'`. But these two commands give me two different outputs. For pip, it shows `tensorflow 1.12.0`. For python, it shows `1.10.0`. Right before using two two commands to check the version, I used `pip install tensorflow=1.10.0`. Before running this install command, I believe my system was installed with 1.12.0. But, how come after running this install command, could these two version checking commands give different answers? Or, did I miss anything there? – Jack Chan Jan 24 '19 at 02:12
`py -3 -c 'import tensorflow as tf; print(tf.__version__)'` worked in my case. – Jithin Jude Apr 15 '19 at 06:42

Almost every normal package in python assigns the variable .__version__ to the current version. So if you want to find the version of some package you can do the following

import a
a.__version__

For tensorflow it will be

import tensorflow as tf
tf.version.VERSION

For old versions of tensorflow (below 0.10), use tf.__version__

python -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 2
python3 -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 3

On Latest TensorFlow release 1.14.0

tf.VERSION

is deprecated, instead of this use

tf.version.VERSION

ERROR:

WARNING: Logging before flag parsing goes to stderr.
The name tf.VERSION is deprecated. Please use tf.version.VERSION instead.

For knowing any version of the python library then if your library is installed using the pip then use the following command.

pip show tensorflow

The Output of the above command will be shown below:-

The tensorflow version can be checked either on terminal or console or in any IDE editer as well (like Spyder or Jupyter notebook, etc)

Simple command to check version:

(py36) C:\WINDOWS\system32>python
Python 3.6.8 |Anaconda custom (64-bit)

>>> import tensorflow as tf
>>> tf.__version__
'1.13.1'

python -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 2
python3 -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 3

Here -c represents program passed in as string (terminates option list)
