ogr2ogr raises "DLL not found" error when run from Pro python environment

Hi All,

Here's what happens:

1. I open the python command prompt in the default arcgispro-py3 environment, which has gdal installed.
2. I run ogr2ogr --help to test/confirm that I can use ogr2ogr.
3. I get, in succession, the 3 error messages below telling me that some dll files are missing:

 

 

Next, I confirmed which version of gdal ships with the Pro environment, and it is gdal 3.4.0:

 

Then, as a test, I created a new, non-ESRI conda environment and installed gdal 3.4.0 in it by running conda install gdal=3.4.0, and that worked, i.e., ogr2ogr works fine from a gdal installation in the non-ESRI environment, but I get the "dll not found" errors when running from the ESRI environment.

 

I looked in environment folder that contains ogr2ogr.exe and, lo and behold, the 3 dll files are in the non-ESRI environment version of gdal, but not in the ESRI environment version.

 

Any reason why the ESRI environment doesn't load these DLLs with gdal? Would it mess things up if I simply copied the 3 DLLs over from the non-ESRI installation of gdal over to the ESRI installation?

 

Also, I didn't always have this problem--I believe it has only come up since updating to Pro 3.0.

 

Thanks,

Interesting to know, but alas does not directly address the issue. As Dan said, Pro uses a different installation of GDAL, which apparently lacks the DLLs needed to run ogr2ogr command line. The link you provided is specific to the gdal python module (not command line ogr2ogr). As Dan and I's thread above describes, my hope is that perhaps there's a way to run ogr2ogr through the python gdal methods, but figuring that out seems time-consuming and will require some sifting through GDAL's API reference.
