Describe the bug

Hello,

I have tried to export the pre-trained PADiM model in OpenVINO format with Post Training Quantization (PTQ) and Accuracy Control Quantization (ACQ).
During execution, I got a ValueError that says 'ImageBatch' object is not subscriptable.

Dataset

MVTecAD

Model

PADiM

Steps to reproduce the behavior

1. Install anomalib using pip.
2. Execute the following command,

AnomalibCLI(
    args=[
        "export",
        "--export_type",
        ExportType.OPENVINO,
        "--compression_type",
        CompressionType.INT8_PTQ,
        "--data",
        MVTec,
        "--data.root",
        f"{project_path}/Padim/MVTec
        "--data.category",
        "dummy",
        "--model",
        "Padim",
        "--default_root_dir",
        str(project_path),
        "--trainer.max_epochs",
        "1",
        "--ckpt_path",
        f"{project_path}/Padim/MVTec/dummy/v0/weights/lightning/model.ckpt",
    ],
)

OS information

OS information:

• OS: [e.g. Ubuntu 20.04]
• Python version: [e.g. 3.10.0]
• Anomalib version: [e.g. 0.3.6]
• PyTorch version: [e.g. 1.9.0]
• CUDA/cuDNN version: [e.g. 11.1]
• GPU models and configuration: [e.g. 2x GeForce RTX 3090]
• Any other relevant information: [e.g. I'm using a custom dataset]

Expected behavior

The model should be converted to OpenVINO format with PTQ which can be verified by successful execution.

What version/branch did you use?
