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
