Add a dataloader for training the decoder ( #57 )
...
* Added dataloader and updated requirements
* Added option to set embedding shard width separately from webdataset shard length.
There must be a better way to do this.
* Changed embedding loader to read using fsspec
* Moved the loader into a more compatible location
* Removed unnecessary package
* Fixed typo (Embeding -> Embedding)
* Simplified example embedding finder code to remove unnecessary get_file_list function
* Added example usage of ImageEmbeddingDataset
* Changed the name of create_dataloader to be more verbose
Added a dataloaders __init__.py
