 ### Ininitailize module with function
 
-As mentioned in prior \[section\](#Customize the initialization method), we could customize our initialization in `init_weights`. To make it more convenient to initialize modules, MMEngine provides a series of **module initialization functions** to initialize the whole module based on `torch.nn.init`. For example, we want to initialize the weights of the convolutional layer with normal distribution and initialize the bias of the convolutional layer with a constant. The implementation of `torch.nn.init` is as follows:
