每个 dataset 可以分成两部分: 原始数据 (raw) data values 和元数据 metadata (a set of data that describes and gives information about other data => raw data)。+-- Dataset | +-- (Raw) Data Values (eg: a 4 x 5 x 6 matrix)| +-- Metadata | | +-- Dataspace (eg: Rank = ...
To iterate over a multi-shot database, we can again instantiate a DataLoader using the customRandomBatchSequenceSampler_multidssampler as well as a customcollate_fn: >>>forxb,ybinloader_train_b:>>>print(xb.shape,yb.shape)>>>breaktorch.Size([513,4,11])torch.Size([513,4,5]) ...

while the second is the one that maps the features of the HDF5 specification to numpy arrays. While PyTables can be thought of as implementing database-like features on top of the HDF5 specification,h5pyis the natural choice when dealing with N-dimensional numpy arrays (not just tables). So...

However, upon updating the database, I have independently launched one or more Array Viewer processes, which are attached to the same database as the simulation program. I believe the sharing is by way of a memory mapped file. With this configuration, during simulation I get an animated...
