How to Install TensorFlow Lite on Raspberry Pi 3 Model B+

Prerequisite(s):

• Enable Swap Space on your Raspberry Pi 3 Model B+
• Install and Configure Python and PIP on your Raspberry Pi 3 Model B+
• Install and Configure Python Virtual Environment on your Raspberry Pi 3 Model B+

Install a few libraries to help with the OpenCV and TensorFlow Lite backend and GUI processing:

pi@raspberry:~ $ sudo apt -y install qt4-dev-tools libatlas-base-dev libhdf5-103

1 - Create and Activate Python Virtual Environment

---

pi@raspberry:~ $ mkdir -p Projects/Python/tensorflow-env
pi@raspberry:~ $ cd Projects/Python/tensorflow-env
pi@raspberry:~ $ python -m venv tensorflow-env
pi@raspberry:~ $ source tensorflow-env/bin/activate
(tensorflow-env) pi@raspberry:~ $

---

2 - Install TensorFlow Lite

---

(tensorflow-env) pi@raspberry:~ $ python3 -m pip install tflite-runtime

---

4 - Verify TensorFlow Working Correctly

---

(tensorflow-env) pi@raspberry:~ $ python

>>> import tensorflow
>>> tensorflow.__version__
'X.X.X'
>>>

Ctrl+D

---

Remove TensorFlow

---

(tensorflow-env) pi@raspberry:~ $ sudo pip uninstall tensorboard
(tensorflow-env) pi@raspberry:~ $ sudo pip uninstall tensorflow
(tensorflow-env) pi@raspberry:~ $ sudo pip uninstall tflite-runtime
