Jeeze and I can't get my pytorch to stop leaking memory. I couldn't imagine trying to drive a car with it

Pytorch is used to train models on servers/cloud, not to drive the car later. The trained model is converted to something native to the embedded environment of the car.

His team is hiring; https://www.tesla.com/careers/job/software-engineerdeeplearn... https://www.tesla.com/careers/job/machine-learninginfrastruc... https://www.tesla.com/careers/job/machine-learningscientista...

lol i just did the interview and failed. had to find shortest path between tesla chargers. all in C++. completed it but failed

Very likely not for the positions above! (they all focus on Python)

Your comments read like /r/RealTesla | TSLAQ fud. Please explain, in detail, what your specific objections are, and how you are more qualified on this subject matter than the presenter.

I am honestly scared even of WayMo that I think unless NHTSA gets its acts together this shit shouldn't be allowed on roads. It's often reactionary - people wait for someone to die and then suddenly you have nervous Musk in front of Congress and such crap. Why wait? Why can't these be regulated before allowing on roads? And no, failover control is not acceptable given the past incidents and deaths.

The only way to train these things is on actual roads. As far as I know, all of these systems require a human driver present at this time. None are fully autonomous.

Meanwhile Waymo is way ahead.

Do you belittle everyone that gets second place in the Olympics because the winner is "way ahead"? Your comment just reeks of anger and hostility. It seems like you'd rather Tesla didn't try at all, and instead we all just give up and go back to the status quo.

Meanwhile General Motors is way ahead.

You seem to use "regulated" as in "forbidden" right now, but maybe I am misreading so can you elaborate? Today thousands are dying every year on the road, are we just forbidding cars entirely? > And no, failover control is not acceptable given the past incidents and deaths. How many incidents/deaths per miles driven? How does it compare to all the other transportation systems?

“Perhaps that’s because, as it turns out, Teslas on Autopilot could have a higher fatal accident rate than those driven entirely by humans.”

Just listening to this talk scares me. The amount of errors - even in a seemingly normal, sunny day - is mind boggling to think people trust this crap. How can we rely on the output of eight cameras? This is not a kid's science project. It's all fancy neural networks until someone dies. Pretty callous and Silicon valley-mindset for such an important and critical function of the car. Will never buy a Tesla after havin…

> mind boggling to think people trust this crap It's also mind boggling to think we currently trust organic tissue to do this crap, some of which is bathed in psychoactive chemicals. And yet we do, and as a result, horrendous catastrophes occur every minute of every day. > It's all fancy neural networks until someone dies No, that can't be the standard, not when people are dying right now in the current regime.

"It's also mind boggling to think we currently trust organic tissue to do this crap, some of which is bathed in psychoactive chemicals."

The appropriate standard for self-driving cars is a sober professional driver, not the average idiot on Saturday night. It isn't unusual for a driver to go a million miles without an accident, when that's their job.

Anyone knows why Andrej's team chooses PyTorch (as oppose to say TensorFlow?)

Not at expert, but as far as I understood PyTorch is much better to build new models, while with tensorflow it’s easier to assemble the predefined blocks. Source: somewhere in the motivations on why Fast.Ai courses switched to PyTorch for the second edition.

Why are people so committed to the idea that self-driving cars are anywhere near human standards? It just seems like a groundless assertion of faith to me.

Professional drivers can go for a million miles without an accident, and I don't believe anyone's autonomous driving software can get within an order of magnitude of that without a disengagement, even in favorable conditions.

You may disagree that a disengagement is equivalent to a human having an accident, but I strongly feel that it is. In either case, you have a situation where the driver reached a point where it was definitively unable to determine an appropriate next action.

No, the appropriate standard for a self-driving car is the driver they replace. If they're safer than whoever would have been driving (be it on a saturday night or not) then they're a net win. Right now the average idiots are buying more Teslas than mail carriers and cab drivers, though that might change I guess.

Numbers are numbers.
