RuntimeError reading BIDS data using mne_bids.read_raw_bids()

[pomeloyou]

Hello！I am learning to use the MNE-Python library for neural signal processing, but an error occurred when reading data using mne_bids.read_raw_bids(). I checked the project history issue and did not find a useful answer. Please help me solve this problem:

• version number：
  • mne 1.6.1
  • mne-bids 0.14
• dataset：
  • ds000117_R1.0.0(https://openfmri.org/dataset/ds000117/)
• code：

data_root = 'F:\\Database\\Multimodal_data\\ds000117_R1.0.0\\derivatives_sub01-04'
data_root = pathlib.Path(data_root)

data_path = mne_bids.BIDSPath(subject='01',
                              session='meg',
                              task='facerecognition',
                              run='01',
                              datatype='meg',
                              suffix='meg',
                              root=data_root
                              )
raw = mne_bids.read_raw_bids(data_path, verbose='error')

• Traceback:

What should I modify to load the data correctly?

Hello! 👋 Thanks for opening your first issue here! ❤️ We will try to get back to you soon. 🚴🏽‍♂️

Hello @pomeloyou, could you please update to the latest versions of mne and mne-bids and try again?
Also, please retrieve the dataset from OpenNeuro; OpenfMRI has been deprecated and the datasets might not conform to the latest BIDS specifications.

Thanks

Thank you for your reply. I'll try it first according to the method you said.
