Exploring the advantages of on-premises Dell PowerEdge servers with AMD EPYC processors vs. the cloud for small to medium businesses’ AI workloads
AI initiatives can bring tremendous value to your business, but you need to support your new AI workloads effectively. That means choosing the best possible infrastructure for your needs—and many companies are finding that the cloud isn’t right for them. According to a recent Rackspace survey of IT executives, 69 percent of companies have moved some of their applications on-premises from the cloud, with half of those citing security and compliance as the reason and 44 percent citing cost.
On-premises solutions provide a number of advantages. With full control over your security infrastructure, you can be certain that all compliance requirements remain firmly in the hands of your IT team. Opting for on-premises also gives you the ability to design your infrastructure to the precise needs of that team and your new AI workloads. Depending on the workload, you may also see performance benefits, along with more predictable costs. As you start to build your next AI initiative, consider an on-premises solution utilizing AMD EPYC processor-powered Dell PowerEdge servers.

Co-Constructing Explanations for AI Systems using ProvenancePaul Groth
Explanation is not a one off - it's a process where people and systems work together to gain understanding. This idea of co-constructing explanations or explanation by exploration is powerful way to frame the problem of explanation. In this talk, I discuss our first experiments with this approach for explaining complex AI systems by using provenance. Importantly, I discuss the difficulty of evaluation and discuss some of our first approaches to evaluating these systems at scale. Finally, I touch on the importance of explanation to the comprehensive evaluation of AI systems.

Neural representations have shown the potential to accelerate ray casting in a conventional ray-tracing-based rendering pipeline. We introduce a novel approach called Locally-Subdivided Neural Intersection Function (LSNIF) that replaces bottom-level BVHs used as traditional geometric representations with a neural network. Our method introduces a sparse hash grid encoding scheme incorporating geometry voxelization, a scene-agnostic training data collection, and a tailored loss function. It enables the network to output not only visibility but also hit-point information and material indices. LSNIF can be trained offline for a single object, allowing us to use LSNIF as a replacement for its corresponding BVH. With these designs, the network can handle hit-point queries from any arbitrary viewpoint, supporting all types of rays in the rendering pipeline. We demonstrate that LSNIF can render a variety of scenes, including real-world scenes designed for other path tracers, while achieving a memory footprint reduction of up to 106.2x compared to a compressed BVH.

Python Requirements File How to Create Python requirements.txt
1. Python Requirements File: How to Create
Python requirements.txt
Ever get confused with all those different Python pieces you need for your project?
Well, good news! There’s a thing called a Python Requirements File that makes it
way easier. Imagine it like a simple list, kind of like your shopping list, but for
computer stuff. It’s called requirements.txt, and it’s here to save you from the hassle
of manually setting up everything.
In this blog, we will discuss how to create these Python necessary records. You can
surely rest; we’ll keep it simple. We’ll explain to you the best method to accomplish
it, as well as a few clever tricks and why it’s such an outstanding idea. People
typically use it with what are known as virtual conditions, but we will stick to the
basics and help you learn how to create and use these Python records. Ready to
make your coding life easier? We should jump in!
2. How to Create a Python Requirements
File
Creating a Python Requirements File is pretty easy and helpful for keeping your
Python project organized. First, go to your project folder and make a new text file.
Make sure to name it requirements.txt and save it in the same place as your Python
files (.py). This file keeps a list of all the important modules your project needs to
work.
Once you have your requirements.txt file, it makes it easy to install the same
modules on other computers. You can also speed things up using a command in the
terminal:
Adding Modules to Your Python Requirements
File
This command collects a list of all the modules you have installed in your project,
including their versions. When you use this command, it puts that list into your
requirements.txt file. This file becomes like a snapshot of your project, making it
simple to share and set up the same environment on different machines.
We’ll also look at some more details, like how to manually install packages in the
terminal, as we go forward. This way, you’ll have a good understanding of how to
handle Python requirements effectively.
Now that you’ve made your Python requirements file, let’s make it even more useful
by adding the specific tools your project needs. It’s easy! Open the text document
and just write down the names of the tools you want. For example, if you want to
3. use the TensorFlow tool, write “tensorflow” on a new line and also mention the
version you want. It would look like this:
Do the same for all the tools you need, like “uvicorn” and “fastapi”. After adding
everything, save the document and close it. This simple step is important because it
tells your project exactly which tools to use and in what version. This makes it easy
for others to set up your project without any problems, no matter where they’re
working from. So, go ahead, add those tools, save, and you’re all set for smooth
installations and teamwork!
Installing Python Packages From a Requirements
File
Once you’ve listed the important modules your project needs in a file called
“requirements.txt,” the next step is to get those modules into your project. We use a
handy tool called pip, which is like a magic helper for installing, updating, and
removing Python stuff.
Here’s how you do it: open a special window on your computer called a terminal or
command prompt. Then, go to the folder where your Python project lives. Once
you’re there, type in this command:
4. This command makes sure all the modules you listed in your “requirements.txt” file
are set up in your project. After you press Enter, you’ll see a bunch of text showing
that the modules are successfully installed, kind of like a receipt.

A good idea is to start with a fresh workspace before installing these modules. If you
ever want to get rid of a module, just use the same command but say ‘uninstall’
instead of ‘install.’ And if you need to update an old module, use ‘upgrade’ instead of
‘install.’
Here’s a cool trick: if you want to see a list of all the Python modules you have in
your project, use the command ‘pip freeze.’ It’s like taking a snapshot of what’s
installed. This way, managing Python modules becomes super easy, making sure your
project stays strong and well-organized.
How to Maintain a Python Requirements
File
Keeping a requirements file is critical for remaining current and ensuring
compatibility with the most recent versions of bundles. If you’ve neglected your
requirements file for a while, don’t worry – follow these steps to get it back in shape:
Step 1: Identify Outdated Packages
Use the command pip list –outdated to get a list of packages that have newer
versions available. This will show you which packages need updating.
5. Step 2: Upgrade Individual Packages
For each outdated package, use the command pip install -U PackageName to
upgrade it. For example:
Command: pip install -U fastapi
This updates the ‘fastapi’ package to the latest version.
Step 3: Upgrade Everything
If you prefer, you can upgrade all packages at once with pip install -U -r
requirements.txt.
Step 4: Check Tests
Ensure that all your tests pass after the upgrades.
Step 5: Update Requirements File
Run pip freeze > requirements.txt to update your Python requirements file with the
latest package versions.
Step 6: Commit and Push Changes
After updating the requirements file, commit the changes using git commit and push
them to the production branch with git push.
6. Bonus Tip: Ensure Dependencies
Check for missing dependencies using python -m pip check. If everything is in order,
you’re good to go!
By following these steps, you maintain a healthy and up-to-date Python
requirements file, ensuring predictable builds for your project.
How to Create Python Requirements Files
After Development
After completing the development of your Python project, it’s important to create a
Python Requirements File to document all the modules and packages your project
relies on. While you can create this file manually by listing each dependency, a
recommended practice is to leverage the pipreqs module, which automates the
process by scanning your project’s imports.
To get started with pipreqs, you need to install it first. Execute the following
command in your terminal or command prompt:
Command: pip install pipreqs
Once pipreqs is installed, you can use it in the command line to automatically
generate a requirements.txt file. For instance, if your project is located at
“/home/project/location,” run the following command:
Command: pipreqs /home/project/location
By running this command, pipreqs will scan your project, identify all the imported
modules, and create a requirements.txt file containing the necessary dependencies.
The terminal output will confirm the successful creation of the requirements file:
Command: Successfully saved requirements file in
/home/project/location/requirements.txt
Using pipreqs streamlines the process of creating a Python Requirements File after
development, ensuring that your project’s dependencies are well-documented and
7. easily reproducible. This automated approach saves time and reduces the risk of
overlooking essential dependencies, contributing to a smoother development and
deployment experience.

Why You Should Use a Python Requirements File
• Python requirements files provide a structured way to list and manage the
dependencies your project relies on.
• They ensure that others can replicate your development environment
accurately by installing the specified modules.
• Using a requirements file with the pip package manager simplifies the process
of installing all necessary dependencies in one command.
• It works with a coordinated effort by allowing team members to work with
similar arrangements of conditions, keeping away from similarity issues.
• Necessities documents empower rendition control for your project’s
dependencies, guaranteeing consistency across different stages of
development.
• Updating or sharing your project becomes more efficient as you can modify
the requirements file without manually tracking and installing each module.
Best Practices for Using a Python Requirements
File
• Group dependencies logically in your requirements file, separating standard
libraries, external packages, and version specifications for clarity.
• Pin versions of your dependencies to ensure consistency across different
environments and avoid unexpected updates.
• Include comments in the requirements file to explain the purpose of specific
dependencies or any additional information helpful for developers.
• Periodically update and review your requirements file to incorporate the latest
versions of packages, enhancing security and leveraging new features.
8. • Combine Python requirements files with virtual environments to isolate
project dependencies, minimizing conflicts with other projects.
• Use ‘pip freeze’ to capture the current environment’s dependencies, aiding in
replicating the environment on different systems.
• If your project has optional features or additional requirements for specific
environments, document them using extras in the requirements file.
• Keep your requirements file under version control, enabling easy collaboration
and tracking changes to dependencies over time.
To sum it up, learning how to create and handle a Python Requirements File is
important for Python developers. Think of it like a simple plan that notes down all
the important parts your project needs to work. Using best practices and tools like
pipreqs makes this process easy, ensuring that your project’s setup is neat and can
be recreated without any hassle.
This file isn’t just for you; it makes sharing your project and working together with
others a breeze. Plus, it helps install and update modules smartly. So, by
understanding and using a requirements file, developers can make their work
smoother, keep things consistent, and boost the chances of their projects being a
success. Consider leveraging professional Python Development Services to enhance
your project’s development and ensure optimal results.
