Ah yes, that's right. Someone needs to implement a way to distinguish between gadget binary files (by parsing the header?) and any old random file.  A pull request that implements this would be very welcome. We have implemented a way to do this for tipsy binary files, so I think it's just a matter of doing the work to get that in place.

Hi Nathan, Jared,

I can confirm that yt.load is not working with the snapshot_010 data on the current tip.  However, the following does work:
ds = yt.GadgetDataset("snapshot_001")

Hi Jared,

Using a pastebin (e.g. paste.yt-project.org), could you paste the full output of "yt version", run from the bash command line?

Best,

Nathan

Hello! I'm a grad student working with gadget, and someone told me today about version 3, which supports gadget! I have never used yt before, as it has never supported sph before, so if this is a really stupid question, please forgive me.  I followed the bootcamp examples just fine, and then tried to load in a gadget snapshot (obtained from the sample datasets portion of yt's website) by doing yt.load("snapshot_010").  I got the following error: yt.utilities.exceptions.YTOutputNotIdentified: Supplied ('snapshot_010',) {}, but could not load!

Then I tried yt.load("snapshot_010", "gadget_binary"), but got the same error. Clearly, I am misunderstanding something very important here.  I looked at the source and saw the GadgetBinaryFile class, so I know it can be done, I just can't figure out how. Very sorry for the bother.  Any help would be greatly appreciated! Thank you very much!
