[ncl-talk] could not find ESMF_RegridWeightGen executable

[Wang, Jiali]

Thank you Laura.

I have loaded ESMF_regridding.ncl in my ncl script, this means the ncl function ESMF_regrid_with_weights is there, and this function will call ESMF_RegridWeightGen.

The problem is when it’s trying to call ESMF_RegridWeightGen, it couldn’t find the executable, but I can see the executable is in the same path as ncl.

I am attaching my ncl script and the data I am using. Can you please take a look and advise?

Thanks again!
Jiali

Hi Jiali:

The function ESMF_RegridWeightGen executable is part of the ESMF library and is not a ncl function: that is the reason why you did not find it in the ncl source code itself. It is the ncl function ESMF_regrid_with_weights that calls the ESMF_RegridWeightGen (that ncl function is in the large ncl script ESMF_regridding.ncl.) So your ncl script should call ESMF_regrid_with_weights, not ESMF_RegridWeightGen.

Hope this helps,
Laura

Hi,

I have been trying on different suercomputers, and all of them look fine (ncl and the excutable are at the same place), but it still says can’t find ESMF_RegridWeightGen executable. I am doing exactly the same thing as this.

https://www.ncl.ucar.edu/Applications/Scripts/ESMF_regrid_36.ncl

Can anyone advise please?
Thanks

Hi NCL users!



I am having a problem running a regrid script.

It says “could not find ESMF_RegridWeightGen executable” after generating the source_grid_file and destination_grid_file and before generating the weights.



Here is what I got (by following up this link https://mailman.ucar.edu/pipermail/ncl-talk/2018-April/011949.html), it seems everything is at the same place but it just can’t find it.



(ncl_stable) [jialiwang at beboplogin4 regrid_test]$ which ncl

/soft/anaconda3/5.2.0/envs/ncl_stable/bin/ncl

(ncl_stable) [jialiwang at beboplogin4 regrid_test]$ ncl -V

6.6.2

(ncl_stable) [jialiwang at beboplogin4 regrid_test]$ env | grep NCARG

NCARG_ROOT=/soft/anaconda3/5.2.0/envs/ncl_stable

(ncl_stable) [jialiwang at beboplogin4 regrid_test]$ which ESMF_RegridWeightGen

/soft/anaconda3/5.2.0/envs/ncl_stable/bin/ESMF_RegridWeightGen

Any suggestions would be appreciated!

Jiali
