"Fixed" the problem, put !apt-get -y install cuda-cudart-10-0
before it launches bootstrap.pl

Sweet! Thanks!!!

Just back from buying a new MB, CPU and RAM. Going offline to rebuild the machine now.

I'll be able to apply the change later today (hopefully)...

Default Any way to reset the uptime?

Sometimes my multiple Colab sessions get "out of sync" — that is, the uptime values are not the same.

Is there any way to stop and restart a notebook so the uptime restarts at zero? So far whenever I restart one, the uptime value resumes where it left off.

I could just let them all run out, but that would waste two sessions while the shortest one runs out (24 hours on the paid tier).

Under the Colab front end's "Runtime" menu, choose "Restart Runtime".

I /believe/ this gives you a freshly launched runtime, but I could be wrong. If that doesn't help, try the "Factory reset runtime" menu time.

Failing all of that not working, try "Manage Sessions" -> "Terminate" on the pop-up window, assuming that option isn't greyed out.

I'd test this myself, but I don't want to risk losing any of my current seven T4s...

BTW, thanks for beta testing the P-1'ing CPU side-job thingy. Looks like it's working nominally.

Default The Colab CPU

The Colab CPU doesn't work like I thought it would. I thought I would get a second executing cell with scrolling output like the GPU process. The CPU process seems to run secretly.

Could you give a simplified explanation as to how this works?

Under the Notebook concept, only a single "Section" can run at a time. Thus, it would be impossible to have a second scrolling section of the output. This interface concept is more designed for education. We're doing this at the sufferance of (and thanks to) Google -- we work with what we've been given...

Thus, the GPU72_TF Notebook launches a subprocess that runs in the background, fetching, working, and reporting on the CPU "work units".

Now that I'm happy that the code is sane (including with the server interaction, and restarting), the next step is to make the progress lines from the CPU process available to the GPU process, to report in the same window output to the humans.

Restart runtime started with the old uptime.
Factory reset runtime started over at zero.
