官方提供的en_PP-OCRv3_rec_train.tar和en_PP-OCRv3_rec_slim_train.tar直接转inference模型成功，但是转nb或者onnx存在相同问题

Same error on my custom finetune model rec_v4.

更新一下paddle2onnx版本，现在这个问题应该修复了

[kevinzezel]

Thanks for the quick response! I'm using Paddle v2.6.0. Should I downgrade to which version?

[GreatV]

Hi @kevinzezel No need to downgrade PaddlePaddle, just use the latest version Paddle2ONNX.

[kevinzezel]

Hi @GreatV! I'm using this command to convert my finetune model to an opt model nb to run in paddle lite:

./opt_linux_aarch64 --model_file=/root/src/pretrain_models/rec_ppocr_v4_NEW_v1_test/inference.pdmodel --param_file=/root/src/pretrain_models/rec_ppocr_v4_NEW_v1_test/inference.pdiparams --optimize_out=/root/src/pretrain_models/rec_ppocr_v4_NEW_v1/inference_opt --valid_targets=arm --optimize_out_type=naive_buffer

Where does paddle2onnx come in?

[GreatV]

@kevinzezel My mistake, you are right, you may need to downgrade the paddle version in this scenario.

Thank you!
