  • What is the difference between __init__ and __call__?
    19 __call__ allows to return arbitrary values, while __init__ being an constructor returns the instance of class implicitly As other answers properly pointed out, __init__ is called just once, while it's possible to call __call__ multiple times, in case the initialized instance is assigned to intermediate variable
  • Python __call__ special method practical example
    IMHO __call__ method and closures give us a natural way to create STRATEGY design pattern in Python We define a family of algorithms, encapsulate each one, make them interchangeable and in the end we can execute a common set of steps and, for example, calculate a hash for a file
  • What does it mean for a class to be callable? - Stack Overflow
    The method that makes instances of a class callable is __call__ So, if your class has an explicit __call__ method, its instances are callable and end of story: when you call the instance, it is the __call__ method that is called That answers half your question - now let's check what the __call__ method on the class of classes does

  • python - When is using __call__ a good idea? - Stack Overflow
    What are peoples' opinions on using the __call__ I've only very rarely seen it used, but I think it's a very handy tool to use when you know that a class is going to be used for some default behav
  • performance - HuggingFaces BertTokenizerFast is between 39000 and . . .
    Having traced the execution path in PDB, the issue arises in the call to model_trainer train(), which I guess ends up calling the lambda used in the declaration of tokenized_dataset I do get the following message: You're using a BertTokenizerFast tokenizer Please note that with a fast tokenizer, using the `__call__` method is faster than using a method to encode the text followed by a call
  • Flask Value error view function did not return a response
    This is not a duplicate, as here the request is a POST, for which it is unintuitive to return something, whereas in the "duplicate", it is a GET and it is fairly obvious that there is a mistake IMHO this is a design issue in flask and I usually fix it with 'return ""' at the end of a post route
