That might theoretically trigger updates of packages on which NVidia stuff depends (through indirection), which will then render your system unusable. You might be lucky, though.

In the case of 'Python Virtual Environments' you'd still have to install another version of Python which is non-trivial with Debian based systems without causing some sort of collision, unless you download the binaries to /usr/ or other bin location as suggested.

I like to use pyenv for this purpose, as it "virtualizes" Python versions by installing them locally as you mention. Then you just point each virtualenv at the Python binary for the version installed via pyenv. pyenv + virtualenv + virtualenvwrapper have greatly reduced Python dependency issues for me.

+1 to pyenv. And it's even better if you combine it with pipenv [1]: pipenv manages dependencies its own file (Pipfile) which can also specify the required Python version. Pipenv integrates with pyenv so if the required Python version is not available it will offer to download and install it.

Tldr; with pyenv and pipenv installing a Python project is just "pipenv install".

Please take a look at Nix. I think you will like it.

I totally agree, at least on the desktop. My /usr isn't required for any of my customers' projects to run, and it probably shouldn't be - I have environments and VMs and containers for all that stuff.

But this is an SBC. It's likely to be configured to run its specific task forever. It should automatically log into the default user's account, and automatically start whatever software you want it to run. Software for it is likely to come from cross-compilers and to be sent over SSH.

It doesn't have hundreds of gigabytes of high-speed storage, the entire OS needs to be copied from a microSD card on every boot, so you don't want to have multiple toolchains on it.

I really like the DietPi [1] environment for these purposes (though it doesn't currently support have the Jetson Nano), the setup scripts make it easy to configure the OS for exactly the tools you want.

Your assertion makes no sense. Let me explain why.

You've adopted a LTS release which was made public 2 years ago, was already a couple of years in the making, and is aimed at establishing a solid and reliable base system that can be targetted by the whole world with confidence.

And knowing that, your idea is to bolt on custom tooling that's not installed anywhere or by no one by default and make it your own infrastructure?

Unless you're planning on managing that part of the infrastructure for your customers to use, your race to catch up with the latest and greatest makes zero sense, and creates more problems than those you believe you're solving.

And no, it's not an infrastructure problem. It's a software engineering problem that's yours in the making. If you seek stability and reliability then you target stable and reliable platforms, such as the stuff distributed by default by LTS releases such as Ubuntu 18.04. because that's what they are used for.

That might theoretically trigger updates of packages on which NVidia stuff depends (through indirection), which will then render your system unusable. You might be lucky, though.

An alternative is to use Docker containers or similar.

Then why pre-install anything? I'm not in the field, but I would think that a lot of people would want to run there Python CV code on it. Or is it, becaue they want you to use CUDA?

Because if you don't have an offering that'll make it do something interesting OOB, it's unlikely anyone would buy it. [bootstrapping from true scratch is typically a nightmare for hobbyists] I shouldn't be quite so negative; NV did put in a lot of effort building up the development kit. ARM Builds of CUDA, drivers, etc. Repos with packages for the job. Tutorials for common tasks, etc. They're really within a hair's…

The raspberry pi didn’t/doesn’t ship with anything and people bought/buy that by the millions

What are the use-cases for a GPU-accelerated single board computer?

Good retro console emulation like the N64 alone may make this a go to for many.

For the price, you might as well do a Mister FPGA build using the DE10-Nano. That’s ~$140 versus the $200 for the Jetson Nano here. And the Mister FPGA, being FPGA based, can avoid most slowdowns software based emulators would have.

If you don't need CUDA, then save money, heat, and support issues associated with a second-string product and just get a rpi4. The entire point of the Jetson is that there's a non sucky GPU that can do AI at the Edge.

Perhaps we would be better off if NVidia just made GPUs for the RPi ...

They are trying to purchase ARM, so I wonder what that means for Mali...
