The last successful build gave a warning at the same point,
H5pyDeprecationWarning: The default file mode will change to 'r' (read-only) in h5py 3.0. To suppress this warning, pass the mode you need to h5py.File()
If the test file is being created here, then perhaps f = h5py.File(fname, 'w') needs to be used here instead of f = h5py.File(fname)Likewise for other uses of h5py.File(fname) elsewhere in the bitshuffle tests.
