make_batch_reader Documentation out of date? seed?

[Data-drone]

I am looking at the documentation here:

https://petastorm.readthedocs.io/en/latest/api.html under make_batch_reader it mentions that there is a parameter seed

I set this is my code:

with peta_conv_train_df.make_torch_dataloader(transform_spec=transform_func,
                                              num_epochs=1,
                                              batch_size=test_batch_size,
                                              cur_shard = 1,
                                              shard_count = 2,
                                              seed=10,
                                              shard_seed=123,
                                              reader_pool_type = pool_type) as reader:

but I get:

TypeError: make_batch_reader() got an unexpected keyword argument 'seed'

It seems to exist in the source code though....

Also what is the difference between seed and shard_seed
