(Deleted) AttributeError: module 'fenics' has no attribute 'HDF5File'

10 months ago by

I installed fenics from source as suggested on https://fenicsproject.org/download/, including support for HDF5.

However, when i try:  outFile = HDF5File(mesh.mpi_comm(), 'filename.h5')
it gives: AttributeError: module 'fenics' has no attribute 'HDF5File'

I rechecked the cmake configuration for dolfin and it is able to detect HDF5 package on my system. Pasting a snippet of the 'cmake .." execution below.
I am new to using fenics. Primarily, I want to be able to write and read function outputs from a solver. From the information I have gathered, one can do this by working with hdf5 format.
In case there better ways to achieve that, please let me know. Thanks.

What do you get with has_hdf5() and has_hdf5_parallel() in dolfin?
Both give me 'False'. Although I am able to store and retrieve data using XDMF format now which solves my purpose, I would still like to know how to fix this issue with HDF5.

Could anyone please suggest what would be the best way to store reference solutions and then be able to load them later during post-processing? I tried the checkpoint writing with XDMF but it does not help, I am unable to load the information that I saved. Thank you for your time.
