Ok, I've put my work in progress in WIP branch here: https://salsa.debian.org/sanvila/python-escript
(I pushed to branch WIP in science-team by mistake a few minutes ago, my apologies, I've already removed that) The LaTeX errors seem fixed, but it still fails to build for me in this way: maximumdownunder/py_src/datasources.py:50: DeprecationWarning: Please import `netcdf_file` from the `scipy.io` namespace; the `scipy.io.netcdf` namespace is deprecated and will be removed in SciPy 2.0.0. from scipy.io.netcdf import netcdf_file *** The MPI_Comm_size() function was called before MPI_INIT was invoked. *** This is disallowed by the MPI standard. *** Your MPI job will now abort. [test-1:780231] Local abort before MPI_INIT completed completed successfully, but am not able to agg regate error messages, and not able to guarantee that all other processes were killed! scons: *** [debian/tmp3/posix/doc/sphinx_api/stuff] Error 14 scons: building terminated because of errors. Please do not make a release from this, even if it works for you. In case this problem is in the "weird" category (works in the buildds, but fails in the AWS instances I'm using), I always offer a VM to reproduce it. Thanks.
