Hi, Everybody!
Does anyone out there have a technique for getting the variance out of
a profile object? A profile object is good at getting <X> vs. B, I'd
then like to get < (X - <X>)^2 > vs B. Matt and I had spittballed the
possibility some time ago, but I was wondering if anyone out there had
successfully done it.
Thanks,
d.

Dear yt
Can current yt calculate 3-D Mass power spectra? I checked the website but
I didn't find any information. I think calculating 3-D Mass power
spectra is a very useful for cosmological simulations. So I guess maybe yt
supports this function now....?
Thanks in advance
Hi,
I have written some new fields in yt/yt/fileds file named as XXX.py, but I have no idea how to make it work correctly like kinetic-energy, thermal-energy etc which can be projected and sliced.
Please help me to work it out!!!
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?
Thanks!

Hello all,
I’d like to extend my congratulations to Ashley Kelly and Corentin Cadiou
for winning the innaugural NumFOCUS new contributor award!
https://numfocus.org/blog/inaugural-numfocus-awards-and-new-contributor-rec…
This is a new award that honors new contributors to NumFOCUS projects. The
yt executive committee nominated Ashley and Corentin and they were both
recognized at the awards dinner on Sunday night after the sustainability
summit.
Let’s all give a warm round of emoji applause!
👏👏👏👏👏👏👏👏
Nathan
Ashley Kelly
Ashley Kelly participated in Google Summer of Code this year with yt via
the NumFOCUS umbrella org. rom the outset, Ashley proposed a very ambitious
plan. Privately I felt that the plan was probably overambitious but with
the expectation that we would likely descope the plan, we decided to press
ahead wit the project. Not only did we not need to descope, In my opinion
Ashley exceeded his original plans. We are now in a much better position to
ship major new features next year thanks to Ashley’s efforts.
Corentin Cadiou
Corentin Cadiou began contributing to yt completely unprompted by any of
the core developers, working from Europe without in-person contact from the
bulk of the yt contributor base in the United States. Corentin has
substantially improved support for simulation data produced by the RAMSES
code, and has contributed a number of other bugfixes, performance
improvements, and nice new features. Corentin has doggedly made sure that
his code gets merged and regularly helps out new users on Slack and the
mailing list. Thanks to his efforts future RAMSES users and users of octree
AMR codes will have a much nicer experience with yt than when he began
contributing.
Hi,
I recently tried to re-install yt on my home directory of a local cluster.
I used the all in one script. After installation I added the yt path to the
PATH environment variable.
The installation looks ok, and the command "yt --help" works. However,
when I try to load data, which worked with a previous installation, I get
this error:
Python 3.6.6 | packaged by conda-forge | (default, Jul 26 2018, 09:53:17)
[GCC 4.8.2 20140120 (Red Hat 4.8.2-15)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import yt
>>> yt.load("disk_mhdhdf5_chk_0020")
python:
/home/conda/feedstock_root/build_artifacts/libnetcdf_1535659474245/work/libsrc4/nc4var.c:431:
nc4_vararray_add: Assertion `var->varid == grp->vars.nelems' failed.
Aborted (core dumped)
Does anyone know what this means? I must have missed something in the
setup. I haven't used conda before.
Thanks!
Paco
Dear yt users,
We are currently testing the revived nightly builds of yt. It would be
enormously helpful to have some real-world testing before making it
official. And we need your help!
We have set up the system so that the latest development version of yt
could be installed from our custom anaconda channel using the command:
>>> conda install -c yt-project/label/dev yt
If you have a few minutes time, you could help testing doing the following:
1. Install yt using the command above in a fresh conda environment.
2. Try some simple yt scripts, like loading a dataset.
3. Report back here whether it is a success and whatever issues you have
encountered. Also include the system information (Linux, macOS, Windows)
and Python version (2.7, 3.5, 3.6, 3.7).
For people more developer-minded, we welcome your comments in the pull
request: yt-project/yt#2030 <https://github.com/yt-project/yt/pull/2030>.
Thanks in advance for your invaluable feedback!
Best regards,
Bili
hi all
i am trying to install rockstar, but make gives a lot of warning then it does work. this is the outcome of make lib in rockstar directory
https://justpaste.it/7d4x7
your input is highly appreciated!

Hi,
I write some new fields in yt/yt/fields named as XXX.py, but I have no idea about how to make it work correctly like yt's density, temperature etc which can be projected or sliced plots.
Hello Mat,
Ok. I will report it on the github site.
Cheers,
