state_dict():返回优化器的状态,包括packed_state和param_groups; load_state_dict():从参数中加载state_dict; zero_grad():将每个参数的梯度设置为None或0; step():为空函数,实现单步优化; add_param_group():向Optimizer的param_groups中添加需要优化的模型参数组; classOptimizer(object):def__init__(self...
Currently, load_state_dict works only when the loaded state_dict and the Module's state_dict match exactly. Problem: For the purpose of fine-tuning or for any slight change in the network, it is not straightforward to load the base layer...

🚀 Feature Right now, module.load_state_dict(strict=False) allows the following: loading a dict with missing parameters loading a dict with more parameters than needed And it returns an object containing the information about what are mis...
