ImportError: DLL load failed

[kikocorreoso]

Hi all,

I'm having problems installing gdal on a W7 32 bits box.

Python 3.6.1 | packaged by conda-forge | (default, May 23 2017, 14:20:21) [MSC v.1900 32 bit (Intel)]

When I try to import it:

from osgeo import gdal

I get the following ImportError:

ImportError                               Traceback (most recent call last)

     23                 fp.close()
     24             return _mod
---> 25     _gdal = swig_import_helper()
     26     del swig_import_helper
     27 else:

     22             finally:

ImportError: DLL load failed: No se puede encontrar el módulo especificado.

Thanks for the hard work.

@kikocorreoso

Please use a dedicated environment, eg:

> conda create -n GDAL python=3.6 gdal
> activate GDAL

If this doesn't help, please post the output of

> conda list

and

> conda config --show

It works like a charm in its own environment.

Is there any compatibility problem or conflict with preinstalled libs if I try to install it in the root?

Thanks again.

@kikocorreoso

Glad it worked!

Installing in root environment is not recommended due to possible clash with defaults-packages. @ocefpaf surely has a more in-depth answer for you.

Thanks again for your time and explanation.

Yep. That is pretty much it 😄

Take a look at the docs on the matter and let us know if it is clear enough. (This problem is so common that we could use a review, and maybe rewrite, of the docs.)
