Looks to me like you are running a training session and the framework expects pre-trained weights for the network.
I'm not familiar with the framework, but if you downloaded a model, check if there's weights available for it. If you are starting for scratch I would assume there's a way to tell the framework to initialize the model with random weights, which is common practice.
However I found at least one notebook online (https://github.com/Seeed-Studio/Seeed_Python_MachineLearning/blob/main/jupyter_notebooks/aXeleRate_lung_segmentation.ipynb) using the same framework, where the error doesn't seem to be stopping the training. Check how they are setting it up there, maybe.
