Develop TensorFlow with Jupyter Notebooks in Okteto Cloud
Machine Learning and Data Analytics are becoming quite popular for mainstream data processing and TensorFlow notebooks are one of the leading platforms in this sector. We are happy to announce that you can now run and develop your TensorFlow programs directly in Okteto Cloud, the development platform for Kubernetes applications 😎!
What are TensorFlow notebooks? TensorFlow notebooks are Jupyter notebooks that integrate the TensorFlow library and the TensorBoard dashboard. Let me explain in a little more detail each one of these components:
- Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations, and narrative text.
- TensorFlow is an open source library, developed by Google, for dataflow and differentiable programming across a range of tasks. It is a symbolic math library, and it is also used for machine learning applications such as neural networks.
- TensorBoard is the tool visualizing TensorFlow programs.
Deploy your TensorFlow Notebook in Okteto Cloud
Okteto Cloud is a development platform for Kubernetes applications. Sign up today to get a free developer account with 4 CPUs and 8GB of RAM. Among other handy features, it has a catalog of applications that you can directly deploy with one-click. Let's use it to deploy your TensorFlow notebook.
Log in to Okteto Cloud and click on the Deploy button on the top left. Switch the deploy method to Deploy from Helm Chart. A dialog will show you the list of available applications you can deploy. Select the tensorflow-notebook application, set the notebook password to something memorable and click the
Your TensorFlow notebook will be running in seconds. The Okteto Cloud UI will show you two links associated with your TensorFlow notebook instance. One is to access the Jupyter notebook and the other one is to access the TensorBoard dashboard:
Cool, no? It cannot get any simpler. No need to manage your own infra, run Docker or write Kubernetes manifests. But that's not all, you can also improve your development workflow for TensorFlow programs using Okteto. Let's see how it works.
- Install the Okteto CLI. Follow this guide if you haven't done it yet.
- Configure Access to your Okteto Cloud namespace using the Okteto CLI or using the Okteto Cloud UI.
TensorFlow Development Environments with Okteto
We have prepared a git repository with a sample TensorFlow program to follow this tutorial. First, get a local version of the sample code by executing the following command:
$ git clone https://github.com/okteto/tensorflow-notebook-getting-started $ cd tensorflow-notebook-getting-started
PASSWORD variable in the
okteto.yml file with the one you picked when deploying your TensorFlow notebook:
name: tensorflow-notebook workdir: /data command: ["jupyter", "notebook", "--allow-root"] environment: - PASSWORD=okteto
Run the following command to activate your TensorFlow development environment:
$ okteto up
✓ Development environment activated ✓ Files synchronized Namespace: irespaldiza Name: tensorflow-notebook [I 13:54:07.261 NotebookApp] Writing notebook server cookie secret to /root/.local/share/jupyter/runtime/notebook_cookie_secret [W 13:54:07.431 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.

okteto up command starts a file synchronization service to keep your changes up-to-date between your local filesystem and your notebook. For example, add data sets or images to your notebook simply by storing them in your local
tensorflow-notebook-getting-started folder. Okteto will make them directly available in your remote notebook. Also, whatever you edit in your Jupyter notebook will be synched back to your local filesystem.
Once you are ready with your changes, run all your cells:
And visualize the measurements and visualizations in the TensorBoard dashboard:
Finally, commit your changes when needed, no need to export/import your programs anymore 🚀!
Kubernetes has the potential to be a great machine learning platform, giving quick access to specialized hardware, and sharing your infrastructure by everyone in your team. Okteto simplifies your Kubernetes journey by making developers and data scientists abstract away from the low-level details.
