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

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 2python3 -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 tensorflowtensorflow (0.9.0)`

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 aa.__version__`

For tensorflow it will be

`import tensorflow as tftf.version.VERSION`

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

If you have installed via pip, just run the following

`$ pip show tensorflowName: tensorflowVersion: 1.5.0Summary: TensorFlow helps the tensors flow`
