Installing nachos

Normal install

To install the latest version of nachos:

pip3 install --user --upgrade git+https://github.com/pierre-24/nachos.git

Note that --user allow you to install the package without being superuser (see here). You will probably need to add $HOME/.local/bin to $PATH for this to work:

echo 'PATH=$HOME/.local/bin:$PATH' >> ~/.bashrc

On the other hand, you can install it in a virtualenv (see below).

(optional) Patching Dalton

By default, it is possible to perform numerical differentiation with Dalton, but the following patch will improve different stuffs:

• Increase values of some constants, so that more frequencies and responses functions can be computed in the same input ;

• Outputs responses functions in a better place (DALTON.PROP in the archive), with more digits (important for the accuracy) ;

• Allow to compute numerical differentiation of gamma (because it is otherwise not possible, since only the components that participate to \(\gamma_{||}\) are computed).

You can find the patch and instructions there.
