Import Error: DLL load failed. Orekit about orekit-feedstock HOT 6 CLOSED

Hi!
Yes it is because orekit and some other conda packages needs the environement to be "activated" in order to get the right environment variables. This is automatically done when opening through the conda prompt. Pycharm and spyder accesses the python binary directly normally without activating the environment.

To solve this, one can either activate the environment prior to starting pycharm or spyder through the command line or use a package called conda-wrappers that makes "pseudo" binaries for the environment that automatically also activates it. These are accessed in the scripts/wrappers/ directory in your python installation after installing the conda-wrappers package.

There are some more info about installation and if you want to specify the paths manually at

Closing as no further response and very likely the root cause.

Hello Petrus,

I was indeed trying to follow the same guidelines to point Spyder to the wrapper in Scripts/wrappers/conda/python.bat, but a .bat file is not considered an interpreter by Spyder? I am very new to python so I apologize if that sounds weird.
Indeed, if I open Spyder from the anaconda prompt, no problems importing orekit.
If I open spyder from the command prompt or through shortcut, it gives me this error, even though I only have one env, base, and it is activated.
In any case I can keep launching Spyder from conda prompt. Activation of python environments has really bugged me so I would like to get to the bottom of it

Hi @quamobrem

Yes it is the activation of environement thing you are experiening, this needs to be done prior to using orekit. If you launch spyder from the start menu directly this is not done. You can also launch spyder from the anaconda-launcher application, that is activating the environment as well.

Thank you very much for your help Petrus, cheers!
