Args: url (str): The location where we find the weights. transforms (Callable): A callable that constructs the preprocessing method (or validation preset transforms) needed to use the model. The reason we attach a constructor method rather than an already constructed object is because the specific object might have memory and thus we want to delay initialization until needed. meta (Dict[str, Any]): Stores meta-data related to the weights of the model and its configuration. These can be informative attributes (for example the number of parameters/flops, recipe link/methods used in training etc), configuration parameters (for example the `num_classes`) needed to construct the model or important meta-data (for example the `classes` of a classification model) needed to use the model. url transformsmetaotherreturncFt|tstS|j|jk7ry|j|jk7ryt|j t rt|j t r|j j|j jk(xr\|j j|j jk(xr-|j j|j jk(S|j |j k(S)NF) isinstancerNotImplementedrrrrfuncargskeywords)selfrs U/var/www/html/eduruby.in/venv/lib/python3.12/site-packages/torchvision/models/_api.py__eq__zWeights.__eq__*s%)! ! 88uyy  99 " doow /Ju?O?OQX4Y$$(8(8(=(==JOO((E,<,<,A,AAJOO,,0@0@0I0II  ??e&6&66 6N) __name__ __module__ __qualname____doc__str__annotations__r dictr boolr(r)r'rrs5  H sCx.7C7D7r)rceZdZdZededefdZdededeeeffdZ defdZ e d Z e d Z e d Zy ) raM This class is the parent class of all model weights.
