One of the best ways for machine learning (ML) practitioners to use Amazon SageMaker is to train and deploy ML models using SageMaker notebook instances. The SageMaker notebook instances help create the environment by initiating Jupyter servers on Amazon Elastic Compute Cloud (Amazon EC2) and providing preconfigured kernels with the following packages: the Amazon SageMaker Python SDK, AWS SDK for Python (Boto3), AWS Command Line Interface (AWS CLI), Conda, Pandas, deep learning framework libraries, and other libraries for data science and machine learning.
To train, validate, deploy, and evaluate an ML model in a SageMaker notebook instance, use the SageMaker Python SDK. The SageMaker Python SDK abstracts AWS SDK for Python (Boto3) and SageMaker API operations. It enables you to integrate with and orchestrate other AWS services, such as Amazon Simple Storage Service (Amazon S3) for saving data and model artifacts, Amazon Elastic Container Registry (ECR) for importing and servicing the ML models, Amazon Elastic Compute Cloud (Amazon EC2) for training and inference.
You can also take advantage of SageMaker features that help you deal with every stage of a complete ML cycle: data labeling, data preprocessing, model training, model deployment, evaluation on prediction performance, and monitoring the quality of model in production.
This Get Started tutorial walks you through how to create a SageMaker notebook instance, open a Jupyter notebook with a preconfigured kernel with the Conda environment for machine learning, and start a SageMaker session to run an end-to-end ML cycle. You'll learn how to save a dataset to a default Amazon S3 bucket automatically paired with the SageMaker session, submit a training job of an ML model to Amazon EC2, and deploy the trained model for prediction by hosting or batch inferencing through Amazon EC2.
This tutorial explicitly shows a complete ML flow of training the XGBoost model from the SageMaker built-in model pool. You use the US Adult Census dataset, and you evaluate the performance of the trained SageMaker XGBoost model on predicting individuals' income.
From what I checked (utils and keras), the save_model function requires at least a model argument and a file path. According to the code snippet that you provided, only the model was provided. Possibly your function defaults to a directory but without knowing the provider, it is difficult to say.
I then tested loading it into a new jupyter notebook and while it seems to load successfully, I'm not sure how to interact with it from the notebook. This is my first time to attempt such a thing so I'm lost as to how to begin.
I am training PyTorch deep learning models on a Jupyter-Lab notebook, using CUDA on a Tesla K80 GPU to train. While doing training iterations, the 12 GB of GPU memory are used. I finish training by saving the model checkpoint, but want to continue using the notebook for further analysis (analyze intermediate results, etc.).
When you have an error in a notebook environment, the ipython shell stores the traceback of the exception so you can access the error state with %debug. The issue is that this requires holding all variables that caused the error to be held in memory, and they aren't reclaimed by methods like gc.collect(). Basically all your variables get stuck and the memory is leaked.
If you have a variable called model, you can try to free up the memory it is taking up on the GPU (assuming it is on the GPU) by first freeing references to the memory being used with del model and then calling torch.cuda.empty_cache().
Context: I have pytorch running in Jupyter Lab in a Docker container and accessing two GPU's [0,1]. Two notebooks are running. The first is on a long job while the second I use for small tests. When I started doing this, repeated tests seemed to progressively fill the GPU memory until it maxed out. I tried all the suggestions: del, gpu cache clear, etc. Nothing worked until the following.
Note that I don't actually use numba for anything except clearing the GPU memory. Also I have selected the second GPU because my first is being used by another notebook so you can put the index of whatever GPU is required. Finally, while this doesn't kill the kernel in a Jupyter session, it does kill the tf session so you can't use this intermittently during a run to free up memory.
The tensorflow version on google colab is too high to produce comptabible versions of models to use with Fiji. The version of python on colab is too high to install older versions of tensorflow like 1.15.
I also found this (Saved Model for ImageJ Plugin gives error Issue #90 stardist/stardist GitHub) option to convert a newer tensorflow model to an older one but keep getting a range of errors trying to run the script.
Has anyone got a simple solution to this? We already have fairly comlex code in Fiji doing everythign we need, it just would be better to have a custom model to use for stardist to make everyting more accurate.

In order for your script to run, you need to be working in an environment configured with the dependencies and libraries the code expects. This section helps you create an environment tailored to your code. To create the new Jupyter kernel your notebook connects to, you'll use a YAML file that defines the dependencies.
Add code to start autologging with MLflow, so that you can track the metrics and results. With the iterative nature of model development, MLflow helps you log model parameters and results. Refer back to those runs to compare and understand how your model performs. The logs also provide context for when you're ready to move from the development phase to the training phase of your workflows within Azure Machine Learning.
Now that you've tried two different models, use the results tracked by MLFfow to decide which model is better. You can reference metrics like accuracy, or other indicators that matter most for your scenarios. You can dive into these results in more detail by looking at the jobs created by MLflow.
For now, you're running this code on your compute instance, which is your Azure Machine Learning development environment. Tutorial: Train a model shows you how to run a training script in a more scalable way on more powerful compute resources.
This tutorial showed you the early steps of creating a model, prototyping on the same machine where the code resides. For your production training, learn how to use that training script on more powerful remote compute resources:
Construct the query and preview the resulting DataFrame with the following code. Here we're getting 4 features from the original dataset, along with baby weight (the thing our model will predict). The dataset goes back many years but for this model we'll use only data from after 2000:
Next, extract the label column into a separate variable and create a DataFrame with only our features. Since is_male is a boolean, we'll convert it to an integer so that all inputs to our model are numeric:
AI Platform Notebooks has a direct integration with git, so that you can do version control directly within your notebook environment. This supports committing code right in the notebook UI, or via the Terminal available in JupyterLab. In this section we'll initialize a git repository in our notebook and make our first commit via the UI.
Check the box next to your demo.ipynb notebook file to stage it for the commit (you can ignore the .ipynb_checkpoints/ directory). Enter a commit message in the text box and then click on the check mark to commit your changes:
We'll use the BigQuery natality dataset we've downloaded to our notebook to build a model that predicts baby weight. In this lab we'll be focusing on the notebook tooling, rather than the accuracy of the model itself.
Then we'll compile our model so we can train it. Here we'll choose the model's optimizer, loss function, and metrics we'd like the model to log during training. Since this is a regression model (predicting a numerical value), we're using mean squared error instead of accuracy as our metric:
Now we're ready to train our model. All we need to do is call the fit() method, passing it our training data and labels. Here we'll use the optional validation_split parameter, which will hold a portion of our training data to validate the model at each step. Ideally you want to see training and validation loss both decreasing. But remember that in this example we're more focused on model and notebook tooling rather than model quality:
Now that you've made some changes to the notebook, you can try out the git diff feature available in the Notebooks git UI. The demo.ipynb notebook should now be under the "Changed" section in the UI. Hover over the filename and click on the diff icon:
The What-If Tool is an interactive visual interface designed to help you visualize your datasets and better understand the output of your ML models. It is an open source tool created by the PAIR team at Google. While it works with any type of model, it has some features built exclusively for Cloud AI Platform.
The What-If Tool comes pre-installed in Cloud AI Platform Notebooks instances with TensorFlow. Here we'll use it to see how our model is performing overall and inspect its behavior on data points from our test set.
To make the most of the What-If Tool, we'll send it examples from our test set along with the ground truth labels for those examples (y_test). That way we can compare what our model predicted to the ground truth. Run the line of code below to create a new DataFrame with our test examples and their labels:
