Reproduce the failing `CNNExplainer(model, imagenet_class_labels)` line using the linked `.pkl` file and capture the complete TypeError, since the issue does not include its message or name a source file or test. Trace the constructor inputs to identify the incompatibility; done means the provided model and ImageNet labels can initialize `CNNExplainer` successfully.
