linux ubuntu tensorflow.keras加载模型报错（代码自动下载模型）：
代码：
from omegaconf import OmegaConf
cfg = OmegaConf.from_dotlist([f"model.model_name={model_name}", f"model.img_size={img_size}"])
from tensorflow.keras import applications
base_model = getattr(applications, cfg.model.model_name)(include_top=False,input_shape=(cfg.model.img_size, cfg.model.img_size, 3),pooling="avg")
报错：

Exception: URL fetch failure on https://storage.googleapis.com/keras-applications/efficientnetb3_notop.h5: None -- [Errno -2] Name or service not known
解决：手动下载这个模型（https://storage.googleapis.com/keras-applications/efficientnetb3_notop.h5），放到 ~/.keras/models/（也即/home/user1/.keras/models/）目录下即可。
