Install SimPEG on windows

[jc-barreto]

Hello,

I'm trying to install SimPEG, but I'm getting an error.
When I try through the prompt line, with the command pip install SimPEG, installs all the packages but when arrives in the discretize I get an error:

And when I try to run the setup.py file I have the same error:

I already installed the Microsoft Visual C++ 2008 from here https://www.microsoft.com/en-ca/download/details.aspx?id=29
But still getting the error...
Someone knows how I can fix this?

Thanks a lot

Hi @jc-barreto, can you try installing the latest Visual C++ from here: https://support.microsoft.com/en-ca/help/2977003/the-latest-supported-visual-c-downloads (should be 2017) and give it another try?

Let us know how it goes!

@jc-barreto : I had users being more successful with the Build Tools, although it is a larger installation.

Hello,
Thank you very much.
I think is done. The second tip, installing just the Build tools didn't work, so I installed all the Visual Studio 2017.

Now I'm trying to run SimPEG to see if the installation was really successful, BUT I'm a layperson on this subject. I have tried to run the DC_inversio_2D_example from notebooks and I got an error, so I don't know if is because the installation wasn't successful or it is because I'm running the notebook wrong...

Some tip?

@jc-barreto 👍 Ok great, thanks for letting us know about Visual Studio.

Can you try opening a command window and type:

pip install pymatsolver

Then restart your kernel and run all

[jc-barreto]

Thanks.

I did that...

But in my pymatsolver folder doesn't exist "PardisoSolver" I don't know why...

[fourndo]

Same here

Hmmm not too sure. Let me dig into this...

@jc-barreto How about pyMKL, can you try a pip install?

pip install pyMKL

[jc-barreto]

Yeah... I tried this before too =(

I didn't install Python through anaconda, I already had installed when I installed anaconda, do you think this matter?

[lheagy]

Hi @jc-barreto: can you try conda install mkl? (mkl is distributed through conda and needs some of the conda libraries and I don't think the pip install can handle this)

I just saw your updated message - installations and managing your environment will be much(!) easier if you use ananconda to install python (https://www.anaconda.com/download). Use python 3.6 and the windows install

[jc-barreto]

Hello,
I uninstalled python and anaconda, and then installed python through Anaconda.
Now the example it's working. Thank you! =)

[lheagy]

Excellent, I am glad you are up and running @jc-barreto!!

@xtt790894620 Looks like VS is still giving you trouble indeed.
I am not sure which one you have downloaded and installed, but this one works on all PCs I seen so far:
Visual Studio Community

Make sure during the installation that you've selected the Desktop develpmoent with C++ option.
