Dear Prof. Bierlaire and other Biogeme users

I have been trying to install Pandas Biogeme on a Windows 7 computer (64 bit), and I get the following error:

(base) C:\WINDOWS\system32>pip install biogeme

I am stuck. Please could you help me get unstuck? I attach a more detailed session log in case this is of any use.

I look forward to your reply.

Kind regards

As mentioned in the video, the compiled version of biogeme for windows is available for python 3.7.

If you want to build it from source, you need to know what you are doing. In particular, you need a compiling environment on your computer.

Anyway, in this case, as explicitly said in the errors, it appears that the package unidecode is not present. You need to install it first using

pip install unidecode.

Many thanks for your prompt and helpful response. That has successfully got me unstuck. I created a Python 3.7 environment in Anaconda and then opened the terminal within that environment to do the installation. This time the installation went smoothly. I didn't even require special permissions.
