Error with h5fortran

[EmilioEchevarria]

Hello there,

I recently started using neural-fortran, which has h5fortran as a dependency. When trying to run one of the neural-fortran examples, I get an error related to h5fortran, and I'm wondering if anybody could please help me debug this. The error I'm getting is:

ERROR STOP h5fortran:open: HDF5 library initialize

and it happens when I try to load a pre-trained neural network model (.h5 extension file). It seems to be related to this part of the code:

h5fortran/src/utils.f90

Lines 73 to 80 in 671dfa2

	!> Initialize FORTRAN interface
	!! HDF5 1.14.0 introduced bug that if H5open_f is called more than once,
	!! it will error.
	if (.not. hdf5_is_initialized()) then
	if(self%debug) print '(a)', 'TRACE:h5fortran:h5open: initializing HDF5 library'
	call H5open_f(ier)
	call estop(ier, 'h5open:H5open HDF5 library initialize', filename)
	endif

But I don't quite get it, what is this error exactly? Why would hdf5_is_initialized() fail?

I'm working in Linux, with gfortran and gcc version 12.3.0, and I installed hdf5-1.14.0 with ./configure --prefix=/path/to/hdf5 --enable-fortran. Any advice/comment will be greatly appreciated.

Cheers,
Emilio

Apologies, I just saw this: #42 (comment)

Changing the hdf5 version to 1.12.0 fixed it :)
