Perplexity validation on PG19 error and Passkey Retrieval error

[khfs]

I followed the environment setup in the readme exactly. When performing Perplexity validation on PG19, the only difference from the original code is that I loaded the model from a local path and set the device to 'cpu' to see the exact error messages. My command line was:

python test_ppl.py --seq_len 16384 --scale 7b --data_path pg19_llama2.validation.bin

The terminal output was:

The argument trust_remote_code is to be used with Auto classes. It has no effect here and is ignored.

When performing Passkey Retrieval, the only difference from the original code is that I loaded the model from a local path. My command line was:

python test_passkey.py --seq_len 16384 --scale 7b

Hi ! Have you verified your code without the chunkLlama monkey patch?

[khfs]

Yes, I commented out line 85 in test_ppl.py and got the same error message. Later, after comparing this code with the eval.py code of LongLoRA, I found that changing np.uint32 to np.uint16 on line 98 of test_ppl.py allowed the code to run. However, the result of running CHUNKLLAMA2 7B was {"seq_len": 16384, "gpu": "1", "data_path": "pg19_llama2.validation.bin", "scale": "7b", "pretraining_length": 4096, "ppl": 1803.4413082318101}. Obviously, this result is not correct, and I don't know what other issues exist in the code.

Thank you for letting me know! I think this issue is caused by mistakenly uploading the files using Llama3 tokenizer. I will check it right now.

Hi! Changing data = {'val': np.memmap(data_path, dtype=np.uint32, mode='r')} -> data = {'val': np.memmap(data_path, dtype=np.uint16, mode='r')} works for me. Remember not to comment out this line: replace_with_chunkllama(args.pretraining_length, args.pretraining_length//4)

Although this allows the code to run, the result I obtained is {"seq_len": 16384, "gpu": "1", "data_path": "pg19_llama2.validation.bin", "scale": "7b", "pretraining_length": 4096, "ppl": 1803.4413082318101}, where the PPL is too high. Therefore, I believe there is still an issue with the code. I am curious about your results.

[ChenxinAn-fdu]

I have updated the code. Plz try the newest version🤣.

[khfs]

Thank you for your response regarding the validation on PG19 and I am currently testing the latest version of the code. How can I resolve the error related to the passkey retrieval?

test_passkey.py has also been updated!
