UnicodeDecodeError at the stage of fine-tuning a pre-trained SQA model #146

Closed Otax-kaz closed 3 years ago

Otax-kaz commented 3 years ago

I was studying table question answering and was interested in your research. Therefore, I tried to reproduce the experiment.

I'm using an Ubuntu container with Docker. The package installation and tox execution are complete. I downloaded the SQA dataset and the model tapas_sqa_inter_masklm_tiny_reset and tried fine tuning, but an error occurred.

Looking at the results of other people's executions on the Internet, I don't think there is any particular difference. Also, the dataset's tsv file doesn't seem to contain any weird characters.

This is the command I executed.↓

python3 tapas/run_task_main.py \
>   --task="SQA" \
>   --input_dir="data/SQA_Release_1" \
>   --output_dir="output_dir" \
>   --bert_vocab_file="tapas_sqa_inter_masklm_tiny_reset/vocab.txt" \
>   --mode="create_data"

This is the error that occurred.↓

I'm sorry it's hard to understand. I would appreciate it if you could answer.

Hi,

I'm trying to reproduce the error but I couldn't. Can you check your input files (SQA data) if they are correctly loaded? Also can you check which file/files outputs this error: can you try putting one by one in the input directory?

Can you find the character that cannot be read: It happened to me when downloading (using different machine type) some public datasets (different from SQA) that the escape character is coded in a wrong way. I suspect that you have one character that is badly encoded. If you know what it is you can change it to the correct one.

Thanks, Syrine

Thanks for your answer.

When I was checking the processing for the input file, I found that this program was reading the invisible file. The invisible file is "._{original filename}" and the encoding seems to be "Windows-1252". When I ran the python program after removing this file from "input_dir", the program worked without error.

I wasn't paying attention to the fact that I downloaded SQA file on a MacOS machine. I'm sorry I was confused by this lack of confirmation.

I appreciate it very much!!
