No command 'toco' found

I'm trying convert my newly trained mobilenet model to tflite for using it with an Android App by following the Google codelabs. https://codelabs.developers.google.com/codelabs/tensorflow-for-poets-2-tflite/index.html#3

I'm on a Ubuntu 16.04 LTS Machine.It say's

No command 'toco' found

Google told me that toco does not work on Windows, but I'm on a Ubuntu machine and my TensorFlow works perfecly for training and inference.

Since TensorFlow works and toco comes along with TensorFlow, toco should ideally work and it doesn't.

It is installed as a command line script, with TensorFlow, so you can easily access it.

Need help fixing the issue with toco(TensorFlow Lite Optimizing Converter) so that I can convert my model to a .lite file and run it on Android device.
