While reading the
h5py docs, I came upon a discussion about creating empty (or null) datasets. (There is also mention of empty/null attributes, but of less interest.) Ref: Creating and Reading Empty (or Null) datasets and attributes. Per the doc, an empty dataset is “a dataset with an associated type, but no data, and no shape”.
From my testing, it appears, you can’t modify the shape or add data to the dataset. Is that correct?
If so, what is the purpose of an empty/null dataset?
