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 transformsmeta)otherreturncCst|tstS|j|jkrdS|j|jkr.dSt|jtrvt|jtrv|jj|jjkot|jj|jjkot|jj |jj kS|j|jkSdS)NF) isinstancerNotImplementedrrrrfuncargskeywords)selfrr%`/var/www/html/stable-diffusion-webui/venv/lib/python3.9/site-packages/torchvision/models/_api.py__eq__(s   zWeights.__eq__N) __name__ __module__ __qualname____doc__str__annotations__rr rboolr'r%r%r%r&rs rc@sneZdZdZeeedddZeee efdddZ e dd d Z e d d Z e d dZe ddZdS)raM This class is the parent class of all model weights.
