install on Mac via pip

Hi all,

I'm new to Biogeme and am trying to install in on my MacBook Pro for the first time. I've got pip up to date (version 18) but when I install biogeme, I got the following:

Any ideas? I don't have Xcode on my MacBook, though.

cheers,

The precompiled version for Mac is for python 3.7.0. If you have a different version of python, pip tries to install it from sources. In that case you need Xcode.

When I got this error I solved it by installing the package unidecode (>> pip install unidecode)

Not fully confident that this is the way to go however as I run into Xcode issues later on. I do not want to install python 3.7 as many libraries are not updated for it yet. Now trying to see if I can get biogeme working by installing it on linux using a virtual machine…

Thanks a lot, Michel. It worked after updating to Python 3.7 on my Mac. ^_^

Hi,

Just a note after my successful installation with Python 3.7. This works well with Biogeme but the upgrade of Python to 3.7 killed my TensorFlow. The current Python 3.7 doesn't (fully) support TensorFlow (1.12). So I ended up installed Python 3.6 and TensorFlow in a separate environment. I should have installed Python 3.7 in a new environment with Biogeme!

cheers,

W.

Thanks.

Note that it should also be possible to install biogeme from sources, but it may require some “hacking”.
