Re: [yt-users] Saving clump data

Hi Britton, Jose created an issue and I made a pull request to fix this: https://github.com/yt-project/yt/pull/1567 -Nathan On Wed, Sep 27, 2017 at 11:36 AM, Britton Smith wrote:

Hi Jose,

If I missed an update to this, please disregard. In any case, I am pretty sure this is happening because the "x", "y", and "z" fields get written automatically and so when you specify them, it is trying to write them twice. This is definitely a bug and should be easily fixed, but in the mean time you should be able to get around this by removing those fields from your field list.

Hi Jose,

This feels like a bug.

Any chance you can make a runnable example that triggers this error? Please use one of the sample datasets at yt-project.org/data or if that’s not possible one of your own datasets, which you can share with us using the yt curldrop (see docs.hub.yt).

Once we have a way to reproduce the error, please go ahead and file an issue about this on yt’s github so we don’t lose track.

Hello yt users,

I have tried to save a clump dataset but I'm getting the following error:

*Code:* *...*

*fn=master_clump.save_as_dataset(fields=["cell_mass", "total","x","y","z","velocity_x","velocity_y","velocity_z"])* *print(fn)*

*...*

*Error*
