In this episode, we delve into my recent trip to PyCon and PyData 2025 in Germany, sharing insights and experiences from the event.
A Peek Inside PyCon and PyData 2025
The conference, held from Tuesday to Friday in Apil, brought together a diverse group of attendees, including back-end developers, hardware engineers, library creators, and data scientists. The event’s unofficial motto seemed to emphasize the enduring relevance of Python in the ever-evolving landscape of artificial intelligence and machine learning.
Key Themes and Discussions
Diverse Topics and Attendees: The conference covered a broad spectrum of subjects, from large language models (LLMs) and application development to management and transitioning roles within the data science field. A notable session was on moving from a data scientist role to a managerial position, highlighting the complexities and skills needed for such a transition.
Reflecting on Python’s Role: A recurring theme was the acknowledgment of Python’s pivotal role in AI and machine learning. Despite the lack of mainstream media recognition, the community continues to produce valuable content and foster collaboration.
First-Time Participants: Interestingly, a significant portion of the attendees, around 75-80%, were first-timers. This influx of new participants suggests a growing interest and engagement with the Python community.
Conference Experience
The venue, inspired by Hogwarts, featured a labyrinth of staircases and halls, adding a whimsical touch to the event. With 1,500 attendees and 160+ sessions, the logistics were challenging, yet the technical aspects, such as streaming and audio-visual management, were handled adeptly.
Keynote Highlights
Reasonable AI by Kristian Kersting: This keynote explored the integration of neuro-symbolic reasoning into AI models, advocating for a shift away from relying solely on transformers. Kersting emphasized the importance of open-source contributions in advancing AI research.
Hugging Face’s Vision: Another keynote focused on the role of open data and collaborative efforts in Europe to remain competitive in the LLM space. Hugging Face’s initiatives in creating open datasets and facilitating distributed training across data centers were particularly noteworthy.
ESA’s Open Approach: The European Space Agency’s representative shared insights into their open-source methodologies for space exploration data, highlighting the collaborative spirit in scientific research.
Sessions of Interest
While some sessions felt like they could have been conveyed through a blog post, others provided valuable insights into practical applications of data science and engineering. For instance, Schwartz IT’s presentation on predictive stock planning for Lidl (deep and cross networks) and Kaufland showcased the integration of Apache Iceberg and Snowflake in their data pipeline.
Reflections and Takeaways
Overall, the conference was a blend of inspiration and practical knowledge, with networking opportunities being a significant draw. While the quality of sessions varied, the experience of engaging with the global Python community was enriching.
As we wrap up this episode, we’re left reflecting on the value of open-source collaboration and the continuous evolution of Python in the tech landscape. Whether you’re a seasoned professional or new to the field, events like PyCon and PyData offer a unique platform to learn, share, and innovate.
