launcher.py crash on microscope

Added by Anchi Cheng almost 12 years ago

e-mail from Micahel Cianfrocco

So I'm trying to get leginon up and running on a T12 microscope here
at Harvard. It seems that the leginon GUI is installed and works -
when I type 'start-leginon.py' in a terminal, the correct windows pop
up and everything.

but, when I try to start the leginon client on the microscope/camera
computer, the C: terminal window opens and immeidately crashes. i was
able to take a screen shot before the window crashed (see attached).
the may be a few more lines of error that i didn't catch.

- Where would you start to look to understand the basis of this problem?

First, to help catch the exception that caused the crash on the screen, you should start it from python command line. Windows closes the program too fast. The screen capture you've only has trace back.

Instruction is at Test_run_operation_problems
substitute the module import "import start" with "import launcher" in your case.

Please give us a bit more information about the configuration and the installation, such as:

Which version of Leginon are you installing?
Is this an upgrade or are you starting with a clean database?

You said you were able to open Leginon main program by typing start-leginon.py. Does you get as far as acquiring an raw image without saving?

Hi Anchi,

Thank you for the quick response! I'm attaching the full output from the python command line.

As for additional info:
*Leginon version: pre2.2
*RE: upgrade vs. clean database - I don't know, I just started here and this was the latest status. I can try wiping everything to start over if that would help.

Yes, I am able to open the main Leginon program by typing 'start-leginon.py' and I'm also able to open the manual application. However, I can't take any images because the microscope/camera client isn't loaded (because it crashes), so there is no TEM or camera to select.

When and how did you get this version? It looks like an outdated trunk version. The bug you see has been fixed 9 months ago #1792. Update your checkout and try again if you are going to stay on trunk. We normally prefer outside user to stay on the branches for stability, but if you are developing, trunk is the way to go.

It looks like that bug fix didn't get into the releases, though. I will merge the change for the next person to come.
