Error in Installation

[Muhammad Kalifardi]

Hi, is it alright to proceed with this error, or should I revert to an older version of NumPy and SciPy?

I'm encountering the following dependency conflict:

ERROR: pip's dependency resolver does not currently take into account all the installed packages. This is causing conflicts such as:

• Gensim 4.3.3 requires NumPy <2.0, but I have NumPy 2.2.4
• Gensim 4.3.3 requires SciPy <1.14.0, but I have SciPy 1.15.2
• Numba 0.60.0 requires NumPy <2.1, but I have NumPy 2.2.4

Should I downgrade NumPy and SciPy, or is there another way to resolve this?

It seems that you have a package that request an old version of numpy.
The best solution is to create a new clean virtual environment, and install biogeme there. It will not conflict with other packages.
