Hi yt-users!
I have been fiddling some more with yt's clump finder and have another question. I want to use density to find clumps, but want my maximum threshold value to be below the fiducial setting--instead of above the maximum possible density in the code I just want the finder to stop searching at, say 3.2e-24.
The code was working but running out of memory until I set the max threshold, and I now get this error:
....lots of pleasant looking output messages....

I tried to circumvent this error by changing my max to 2e-24 (not a multiple of 2 of 1e-25), and got the same error when the min was 3.2e-24 and the max was 2e-24 (!).
Is there any way I can get around this error and have the clumpfinder stop looking once it has clump edges at my maximum density?

Generally an error like this is due to a bug in yt. I don't know enough about the code you're using to provide useful advice, but perhaps we should be checking if `children` is `None` and doing something else. The "workaround" is likely to fix whatever bug you've run into.

HI Stephanie,
Have you managed to resolve this issue? If so, would you be willing to submit a pull request to get this fix in the main repo? If not, could you post a script that could be used to reproduce this error with some of the public data?

Hi,
Sorry about the crazy delay, here is a script that reproduces the error with the IsolatedGalaxy dataset!
The script is attached. I am happy to help someone look into it, or look more myself with a bit of extra guidance.
Thanks!!

Hi Stephanie,
I actually ran into this bug in the past week. I fixed in for my case by making this change in clump_handling.py
- elif (child._validate()): + elif ((child.children is not None) and child._validate()):
I haven't had the time to submit a PR. If this works for you, let me know, and I can I create one this week.
Thanks, John

Hi John,
Thanks! I *think* it works--here is my only confusion. If I set c_max to some value less than the max density (say, 1e-24 in the code I attached previously), it doesn't crash anymore but it doesn't actually plot a clump contour either. If I set c_max to the max density setting (or I guess a bit above, 10**np.floor(np.log10(data_source[field]).max()+1) ), then I get a contour plotted. Does this seem right to you?
Also, they both give me this message "/mnt/xfs1/home/stonnesen/yt-conda/lib/python3.6/site-packages/matplotlib/contour.py:1180: UserWarning: No contour levels w ere found within the data range. warnings.warn("No contour levels were found" " Even though I seem to have one central contour in the c_max = 10**np.floor(np.log10(data_source[field]).max()+1) case.
Thanks! Stephanie

Hi Stephanie,
While looking into this issue, I found some low hanging refactoring fruit, so I've issued a pull request that cleans things up and takes care of this as well. You can have a look here: https://github.com/yt-project/yt/pull/2045
In running the example you attached, I found that the calculation resulted in a single clump comprised of the entire domain, so the clump annotation may be effectively invisible as it will draw a box around the entire figure. If I used a slightly smaller smaller data container, I was able to see the annotation, so I think things are ok. Let me know if it still doesn't seem right.

Hi John,
Thanks! I *think* it works--here is my only confusion. If I set c_max to some value less than the max density (say, 1e-24 in the code I attached previously), it doesn't crash anymore but it doesn't actually plot a clump contour either. If I set c_max to the max density setting (or I guess a bit above, 10**np.floor(np.log10(data_source[field]).max()+1) ), then I get a contour plotted. Does this seem right to you?
Also, they both give me this message "/mnt/xfs1/home/stonnesen/yt-conda/lib/python3.6/site-packages/matplotlib/contour.py:1180: UserWarning: No contour levels w ere found within the data range. warnings.warn("No contour levels were found" " Even though I seem to have one central contour in the c_max = 10**np.floor(np.log10(data_source[field]).max()+1) case.

Okay, my git skills are not so good, so definitely not *sure*. Just tried to check by doing this:
cd yt-conda/yt (root) -bash-4.2$ git pull https://github.com/brittonsmith/yt.git clurmps From https://github.com/brittonsmith/yt * branch clurmps -> FETCH_HEAD Already up-to-date.
so...I think yes? I also just did the same thing in my script and got the same output. -- Dr. Stephanie Tonnesen Associate Research Scientist CCA, Flatiron Institute New York, NY

Hi Stephanie,
While looking into this issue, I found some low hanging refactoring fruit, so I've issued a pull request that cleans things up and takes care of this as well. You can have a look here: https://github.com/yt-project/yt/pull/2045
In running the example you attached, I found that the calculation resulted in a single clump comprised of the entire domain, so the clump annotation may be effectively invisible as it will draw a box around the entire figure. If I used a slightly smaller smaller data container, I was able to see the annotation, so I think things are ok. Let me know if it still doesn't seem right.

Hi John,
Thanks! I *think* it works--here is my only confusion. If I set c_max to some value less than the max density (say, 1e-24 in the code I attached previously), it doesn't crash anymore but it doesn't actually plot a clump contour either. If I set c_max to the max density setting (or I guess a bit above, 10**np.floor(np.log10(data_source[field]).max()+1) ), then I get a contour plotted. Does this seem right to you?
Also, they both give me this message "/mnt/xfs1/home/stonnesen/yt-conda/lib/python3.6/site-packages/matplotlib/contour.py:1180: UserWarning: No contour levels w ere found within the data range. warnings.warn("No contour levels were found" " Even though I seem to have one central contour in the c_max = 10**np.floor(np.log10(data_source[field]).max()+1) case.

It's my fault. I forgot to remove the imports from ./yt/analysis_modules/level_sets/api.py. If you change the import to "from yt.data_objects.level_sets.api import ..." then it will work. I'll update the PR now.

Okay, so I was trying to figure out why I am getting strange results and went back to the IsolatedGalaxies cookbook case. I am attaching the cut_region verion here. This may be a cut_region problem, not a clump problem, though!
First, I ran the plain old cookbook case and got the same very lovely clumps.
[image: clumps_reloaded_Projection_z_density_cookbook.png]
Then I changed c_max to 2e-24 based on some of the density values I was getting, and got this:
[image: clumps_reloaded_Projection_z_density_max2en24.png] Okay, fine, I just didn't set my limit high enough. So when I run with max = 7e-24:
[image: clumps_reloaded_Projection_z_density_max7en24.png] But, when I select the same (or slightly larger) region with cut_region and the same c_min and c_max (or just using the standard max and min definitions) I cannot find any clumps!
[image: clumps_reloaded_Projection_z_density.png]
Do you think this is a cut_region or a clump_finder problem?
Thanks! Stephanie

Hi Stephanie,
While looking into this issue, I found some low hanging refactoring fruit, so I've issued a pull request that cleans things up and takes care of this as well. You can have a look here: https://github.com/yt-project/yt/pull/2045
In running the example you attached, I found that the calculation resulted in a single clump comprised of the entire domain, so the clump annotation may be effectively invisible as it will draw a box around the entire figure. If I used a slightly smaller smaller data container, I was able to see the annotation, so I think things are ok. Let me know if it still doesn't seem right.

Hi John,
Thanks! I *think* it works--here is my only confusion. If I set c_max to some value less than the max density (say, 1e-24 in the code I attached previously), it doesn't crash anymore but it doesn't actually plot a clump contour either. If I set c_max to the max density setting (or I guess a bit above, 10**np.floor(np.log10(data_source[field]).max()+1) ), then I get a contour plotted. Does this seem right to you?
Also, they both give me this message "/mnt/xfs1/home/stonnesen/yt-conda/lib/python3.6/site-packages/matplotlib/contour.py:1180: UserWarning: No contour levels w ere found within the data range. warnings.warn("No contour levels were found" " Even though I seem to have one central contour in the c_max = 10**np.floor(np.log10(data_source[field]).max()+1) case.
