You can install TensorFlow using the install_tensorflow() function.

As an AI language model, I cannot install TensorFlow on your system. However, I can provide you with the steps to install TensorFlow on your system:

1. Ensure that you have Python 3.5 or later installed on your system.
2. Open the Command Prompt or Terminal and run the following command to install TensorFlow:

pip install tensorflow

3. If you want to install a specific version of TensorFlow, you can run the following command:

pip install tensorflow==<version>

Replace <version> with the version number you want to install.

4. Once the installation is complete, you can test TensorFlow by running the following command:

python -c "import tensorflow as tf; print(tf.reduce_sum(tf.random.normal([1000, 1000])))"

If TensorFlow is installed correctly, you should see a random number printed on the screen.

Note: If you are using a GPU, you will need to install additional dependencies to use TensorFlow with GPU support. You can find more information on the TensorFlow website.
