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

Question

The title says it all. I'm using Ubuntu 16.04 Long Term Support.

Answer 1

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)

Answer 2

Almost every normal package in python assigns the variable .__version__ or 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__ # or a.VERSION

For tensorflow it will be

import tensorflow as tf
tf.VERSION

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

BTW, if you are planning to install tf, install it with conda, not pip

Answer 3

import tensorflow as tf

print tf.VERSION

Answer 4

If you have installed via pip, just run the following

$ pip show tensorflow
Name: tensorflow
Version: 1.5.0
Summary: TensorFlow helps the tensors flow

Answer 5

If you're using anaconda distribution of Python,

$ conda list | grep tensorflow
tensorflow    1.0.0       py35_0    conda-forge

To check it using Jupyter Notebook (IPython Notebook)

In [1]: import tensorflow as tf
In [2]: tf.__version__
Out[2]: '1.0.0'

Answer 6

For python 3.6.2:

import tensorflow as tf

print(tf.VERSION)

Answer 7

I installed the Tensorflow 0.12rc from source, and the following command gives me the version info:

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

The following figure shows the output:

Answer 8

To get more information about tensorflow and its options you can use below command:

>> import tensorflow as tf
>> help(tf)

Answer 9

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)

Answer 10

Easily get KERAS and TENSORFLOW version number --> Run this command in terminal:

[username@usrnm:~] python3

>>import keras; print(keras.__version__)

Using TensorFlow backend.

2.2.4

>>import tensorflow as tf; print(tf.__version__)

1.12.0

Answer 11

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'

Answer 12

For Python 3.6.3:

import tensorflow as tf

print(tf.VERSION)
