import specific module from the class by different name as string variable-CodePudding

I wanna get a module from a class with different name (string variable). However, the content has same form of string as the original module name. For example

import timm
model_configs = timm.models.resnet.default_cfgs['resnet34']  #this one works

target_network_root = 'resnet'
model_configs = timm.models.target_network_root.default_cfgs['resnet34']  #this one doesn't work

Since, the target_network_root can change, I might export another network than resnet, I like to call specific module from timm.models as variable. I really appreciate your support.

CodePudding user response：

You can use getattr()

For example:

getattr(timm.models, target_network_root)

=> timm.models.resnet

CodePudding user response：

if your goal is to load different models form it; this is the right approach:

import timm

list_of_resnet_models = timm.list_models('resnet*',pretrained=True)
#you can fill in this list with some models of your own like: #['resnet34','resnet50','...'] #whatever existing model in timm

model = timm.create_model(list_of_resnet_models[0],pretrained=True)

print(model.default_cfg)

later you can pass different indices of list_of_resnet_models to load other models!
