but i get an error

Hello Efnna,
Model Optimizer does not support .tflite file to IR format conversion natively. Model Optimizer currently only supports a few frozen quantized topologies hosted on TensorFlow Lite site.
This information is available in the subsection "Supported Frozen Quantized Topologies" under the section Supported Topologies.
However, the frozen model file (.pb file) is required for conversion to IR format by Model Optimizer.
Sincerely,
Zulkifli

My model consists of a special directory with a .pb file and several subfolders: variables, assets
