Photo Credit Introduction AWS recently released TorchServe, an open-source model serving library for PyTorch. The production-readiness of Tensorflow has long been one of its competitive advantages. TorchServe is PyTorch community’s response to that. It is supposed to be the PyTorch counterpart of Tensorflow Serving. So far, it seems to have a very strong start. This post from the AWS Machine Learning Blog and the documentation of TorchServe should be more than enough to get you started. But for advanced usage, the documentation is a bit chaotic and the example code suggests sometimes conflicting ways to do things. ...

Photo Credit Introduction The Tensorflow Profiler in the upcoming Tensorflow 2.2 release is a much-welcomed addition to the ecosystem. For image-related tasks, often the bottleneck is the input pipeline. But you also don’t want to spend time optimizing the input pipeline unless it is necessary. The Tensorflow Profiler makes pinpointing the bottleneck of the training process much easier, so you can decide where the optimization effort should be put into. ...

Photo Credit Motivation Apache Airflow is great for managing scheduled workflows, but in a lot of cases, it is an overkill and brings unnecessary complexity to the overall solution. Cron jobs are much easier to set up, have built-in support in most systems, and have a very flat learning curve. However, the lack of monitoring features and the consequential silent failures can be the bane of system admins’ lives. We want a simple solution that can help admins monitor the health of cron jobs in simple scenarios that do not warrant Airflow. The simple scenarios have the following characteristics: ...

This is a short post describing how to use Plotly to make text-heavy charts cleaner in R. Introduction David Robinson presented a beautiful way to visualize the ratings of the Office episodes in this screencast: The chart (shown below) is sufficiently readable when zoomed in on a full HD monitor, but is quite messy when exported to a smaller frame. Moreover, some of the episode names are not displayed (to avoid overlapping). ...

Photo Credit Executive Summary TensorFlow has become much easier to use: As an experience PyTorch developer who only knows a bit of TensorFlow 1.x, I was able to pick up TensorFlow 2.x in my spare time in 60 days and do competitive machine learning. TPU has never been more accessible: The new interface to TPU in TensorFlow 2.1 works right out of the box in most cases and greatly reduces the development time required to make a model TPU-compatible. Using TPU drastically increases the iteration speed of experiments. We present a case study of solving a Q&A labeling problem by fine-tuning the RoBERTa-base model from huggingface/transformer library: Codebase Colab TPU training notebook Kaggle Inference Kernel High-level library TF-HelperBot to provide more flexibility than the Keras interface. (TensorFlow 2.1 and TPU are also a very good fit for CV applications. A case study of solving an image classification problem will be published in about a month.) Acknowledgment I was granted free access to Cloud TPUs for 60 days via TensorFlow Research Cloud. It was for the TensorFlow 2.0 Question Answering competition. I chose to do this simpler Google QUEST Q&A Labeling competition first but unfortunately couldn’t find enough time to go back and do the original one (sorry!). ...
