# 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.

## Answers:

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)
```

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'
```

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__`

```
import tensorflow as tf
print(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
```

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

For python 3.6.2:

```
import tensorflow as tf
print(tf.version.VERSION)
```

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

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

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
```

Easily get KERAS and TENSORFLOW version number –>

Run this command in terminal:

[[email protected]:~] python3

`>>import keras; print(keras.__version__)`

`Using TensorFlow backend.`

`2.2.4`

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

1.12.0

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:WINDOWSsystem32>python
Python 3.6.8 |Anaconda custom (64-bit)
>>> import tensorflow as tf
>>> tf.__version__
'1.13.1'
```

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.
```

Tensorflow version in Jupyter Notebook:-

```
!pip list | grep tensorflow
```

If you have TensorFlow 2.x:

sess = tf.compat.v1.Session(config=tf.compat.v1.ConfigProto(log_device_placement=True))

Another variation, i guess ðŸ˜›

```
python3 -c 'print(__import__("tensorflow").__version__)'
```

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:-

```
Name: tensorflow
Version: 2.3.0
Summary: TensorFlow is an open source machine learning framework for everyone.

```

**For Windows cmd**

```
pip list | FINDSTR tensorflow
OR
pip show tensorflow
```

**For Linux**

```
pip list | grep tensorflow
OR
pip show tensorflow
```

Printing python version in human readable format

```
python -c 'import sys; print(".".join(map(str, sys.version_info[:3])))'
```

The version of **Tensorflow** can simply be checked on **jupyter notebook** using the following simple steps.

```
import tensorflow as tf
print(tf.__version__) # for Python 3
```
