Error creating and exporting TFLite after fine-tuning (using run_squad_v1.py/run_squad_v2.py)

[manojpreveen]

python -m albert.run_squad_v1
--albert_config_file=albert/assets/albert_config.json
--output_dir=albert/output
--train_file=albert/train-v1.1.json
--predict_file=albert/dev-v1.1.json

--export_dir=albert/modelite

The above is the command I ran to finetune Albert-Base on SQuAD1.1
The finetune was successful and I got both tensorflow checkpoints and the model in saved_model format.

When the Conversion of saved_model to TFLite Model step starts, it's throwing out an error as below :

File "/usr/local/share/anaconda3/lib/python3.7/site-packages/tensorflow_core/lite/python/convert_saved_model.py", line 194, in freeze_saved_model
raise ValueError("SavedModels with assets/ directory are not supported.")
ValueError: SavedModels with assets/ directory are not supported.

Is it just happening for me or is it not supported by tensorflow itself yet.
Is there any workaround to create TFLite model.
Please Help.

Thanks.

I'm having a similar problem. We would greatly appreciate some help/guidance!
