Can not read my data

I am a post-graduate who need HDFView for some data processing, but I met a problem below:
after downloading HHFView from HDF5 1.14.0 , I dan start it sucessfully, however, I can`t any data after loading my .h5 file.
how can i deal with it?

Please peruse the documentation of the HDF5 library and the accompanied utility suite. There you find h5dump, which allows you to dump the content of the given dataset if any. Alternative is to use python h5py or julia to inspect the content of the dataset.

By default, HDFView starts in read-only mode. See User Preferences to change the default.
