To check the version of TensorFlow installed, you can use the following code:

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

This will print the version of TensorFlow currently installed on your system.

If you want to check the version compatibility of your TensorFlow code with a specific version of TensorFlow, you can use the following code:

```
import tensorflow as tf
assert tf.__version__ >= '2.0.0', 'TensorFlow version 2.0.0 or newer is required'
```

This code will raise an error if the installed version of TensorFlow is less than 2.0.0. You can change the required version number as needed.

Sure, here's some additional information on related topics:

- Updating TensorFlow:

To update TensorFlow to the latest version, you can use the following pip command:

```
pip install --upgrade tensorflow
```

- Installing specific version of TensorFlow:

If you want to install a specific version of TensorFlow, you can use the following pip command:

```
pip install tensorflow==X.Y.Z
```

Replace `X.Y.Z`

with the desired version number.

- Using GPU with TensorFlow:

To use GPU with TensorFlow, you need to install the GPU version of TensorFlow. You can install it using the following pip command:
