Open your Goggle Drive in your Colab notebook instance.

If you don’t have a Google drive on your local computer, then install it. Google Drive is free.

from google.colab import drive


Mounted at /gdrive

Create, write to, and read out the file on Google Drive.

with open('/gdrive/My Drive/myfile.txt', 'w') as f:
f.write('Hello Google Drive!')
!cat '/gdrive/My Drive/myfile.txt'


Hello Google Drive!

List top-level files on Google Drive.

!ls /gdrive/'My Drive' -lax'


Colab Notebooks'
!cp drive/MyDrive/<file>.py
import <file>


import sys
import <package>

Git is installed in Colab. Most Git commands execute in Colab using shell-escape ! . For example:

!git clone https://github.com/<repo>

How to use Tensorboard in Colab.

A Colab notebook shows step by step how to load Kaggle datasets.

Embedding the Julia language in Colab.

Draw graphs with Graphviz.

The documentation for graphiz.

Install graphviz.

!apt-get -y install python-pydot
!apt-get -y install python-pydot-ng
!apt-get -y install graphviz

Create a graph with Graphviz.

from graphviz import Digraph
dot = Digraph(comment='MLOps Flow as a DAG')
dot.node('D', 'Feature Store')
dot.node('L', 'ML Model Lab')
dot.node('S', 'ML Model Stage')
dot.node('P', 'ML Model Production')
dot.node('M', 'ML Model Monitoring')
dot.edges(['DL', 'DS', 'DP',])
dot.edges(['LM', 'SM', 'PM',])
dot.edge('L', 'S', )#constraint='false')
dot.edge('S', 'P', )# constraint='false')
dot.render('test-output/round-table.jpg', view=True)
