Problem with run_ray_tracing about xrt

[zhangyujun08]

There are two underscores before and after "file"

What is printed by python --version?

[zhangyujun08]

My python version is 3.8.3. Somehow I solved this problem by modifying xrt/runner.py. In line 566: mod = inspect.getmodule(frm[0]) I removed the "[0]" behind "frm". Since I noticed that in the previous line frm = inspect.stack()[1] , inspect.stack() returns a single FrameInfo object but not a list. Maybe it is related to the version of python. Thanks a lot!

According to the documentation, a list of FrameInfo is returned starting from version 3.5.

Don't know what is the problem here but I'll put an extra check there. Please try (the two middle lines are inserted):

    mod = inspect.getmodule(frm[0])
    if mod is None:
        mod = inspect.getmodule(frm)
    runfile = mod.__file__

Thank you for reporting it!

[zhangyujun08]

Thanks a lot for your reply. I added the two lines as you suggested. I have a few other probably related questions. 1. When I used run_ray_tracing to generate XYCplots of some screen in a beamline, sometimes I get plots with only dark background and no contents in it. This is the case when I run e.g. examples\withRaycing\05_QWP\04_collimated_LT.py . But sometimes it works, e.g. for a simplest beamline code generated by xrtQook (following the tutorial in https://xrt.readthedocs.io/qook_tutorial.html#qook-tutorial). 2. The gui of xrtQook does not show any graph. All the buttons are empty without figures in them, although the software itself is working. I am not sure whether these problems are independent or related to each other. Maybe there is something not compatible with my local envirionment? I have tried to either run the scripts in Spyder or in a JupyterLab. Konstantin Klementiev ***@***.***> 于2023年10月18日周三 15:08写道：

When in Spyder, try to run it in external system terminal.

[zhangyujun08]

For xrtQook, I did not run it in Spyder. Just ran python xrtQookStart.pyw at xrt/gui. Konstantin Klementiev ***@***.***> 于2023年10月18日周三 15:49写道：

What happens if you unzip the GitHub xrt package to any user location and run xrtQookStart.pyw from there?

[zhangyujun08]

Yes. That's what I did. I unzipped the package in some directory in my D: disk and ran xrtQookStart.pyw in xrt/gui by command-line terminal without using Spyder. Konstantin Klementiev ***@***.***> 于2023年10月18日周三 16:55写道：

I suspect you have several versions of xrt. Start python from your working directory and type

>>> import xrt
>>> xrt.__file__

Is the library location where you expect it to be? If not, delete it from there and try again.

[zhangyujun08]

Thanks a lot! Indeed there is another xrt installed. After deleting that one, now the gui of xrtQook looks good. However, the problem that XYCplot generates empty figures persists. It is the case when I simply run examples\withRaycing\05_QWP\04_collimated_LT.py , for example. There is no traceback but the figures only have a black background. Could you please also help to point out possible reasons? Thanks a lot! Konstantin Klementiev ***@***.***> 于2023年10月18日周三 20:35写道：

Do you get a single iteration ready? (when you see values for N_all, N_good and Flux)
Try processes=1 in xrtr.run_ray_tracing(plots, repeats=24, ...)

[zhangyujun08]

I think I did not see the values of N_all, N_good and Flux. Originally processes='half'. When I changed it to processes=1, I saw no change of the output. It just outputs some information about the last 10 runs, such as start/stop time, duration, etc. And then the empty figures. Konstantin Klementiev ***@***.***> 于2023年10月18日周三 22:30写道：

Do you see an increased load in a system monitor?

[zhangyujun08]

No obvious change in the system monitor. When I ran the script, only the CPU occupation increased a little for a moment (from ~5% to ~15%). The empty figures came out really fast after running the script. Konstantin Klementiev ***@***.***> 于2023年10月19日周四 00:11写道：

I think that the problem with inspect is indicative of a corrupt python installation. The easiest solution is to install the latest WinPython and forget all the troubles.

[zhangyujun08]

Thanks a lot. I will reinstall python soon and see whether it works. Konstantin Klementiev ***@***.***> 于2023年10月19日周四 15:26写道：

I think the problem is not with python version but rather with proper package management. With WinPython you get a portable system that doesn't need system paths, you can move it to any location, just run its command line shell and you have all the definitions inside. If you want to go a hard way of fixing broken paths and dependences inside your python installation, nobody can help you.

[zhangyujun08]

Thanks a lot. Now I installed WinPython 3.11 and ran the scripts. It successfully worked in the command prompt. However, in Spyder and Jupyter notebook, the problem of empty figures persists. Interestingly, in Jupyter notebook, the problem of inspect occurred again. I copied the xrt into the WinPython notebooks folder and imported xrt from there to run it in Jupyter notebook. I noticed that in the command prompt I can cd to the folders outside the Winpython folder, but in Jupyter I could not go outside the notebooks folder. Probably it also have something to do with my hardware. When I successfully ran it in command prompt, the computer is significantly slowing down. Maybe there will cause some problem when switching to Spyder or Jupyter. Anyway, I can now work with the command prompt and proceed. Thanks again for your kind help!

Make sure you start the WinPython's Spyder, not your previous Spyder version. Spyder's IPython console is not compatible with multiprocessing. So if you want multiprocessing, select the run option "Execute in an external system terminal".

[zhangyujun08]

Yes. I started Spyder in the WinPython folder, but the figures are still empty. Maybe there is still something wrong. Konstantin Klementiev ***@***.***> 于2023年10月26日周四 16:16写道：

How about running the script in an external system terminal (but still from Spyder)?
Alternatively, set processes=1.

[zhangyujun08]

Somehow it also worked... Then probably the problem is in Spyder itself... Konstantin Klementiev ***@***.***> 于2023年10月26日周四 17:36写道：
