Methods Documentation

after_process()

(optional overload)function that runs after processing for optional functionality. intended for optional use as a cleanup function

Parameters:None
batch_process(batch_data)[source]

(required overload)processes a list of data using this block’s algorithm

Parameters:data (list) – list of datums to process
Returns:list of processed datums
Return type:process(list)
before_process(data, labels=None)

(optional overload)function that runs before processing for optional functionality. this function takes in the full data list and label list. does nothing unless overloaded

Parameters:
  • data (list) – list of datums to process
  • labels (list,None) – corresponding label for each datum, None by default (for unsupervised systems)
label_strategy(labels)

runs self.labels

labels(labels)

(optional overload) returns all labels for input datums or None

process_strategy(data)

runs self.batch_process

rename(name)

Renames this block to the given name

Parameters:name (str) – the new name for your Block
Returns:object reference to this block (self)
Return type:ip.Block

Note

unlike naming your block using the name parameter in instantiation, imagepypelines will not guarantee that this name will be unique. It is considered the user’s responsibility to determine that this will not cause problems in your pipeline.

train(train_data, train_labels)[source]

(optional or required overload)trains the block. overloading is required if the ‘requires_training’ parameter is set to True

users are expected to save pertinent variables as instance variables

Parameters:
  • data (list) – list of datums to train on
  • labels (list,None) – corresponding label for each datum, None by default (for unsupervised systems)
Returns:

None
