ImportError: No module named 'bids'

Hello fmriprep experts,

‘bidskit’ is throwing an error when I tried to convert dicom to BIDS:

“bidskit /home/xxx/yyy/CSRI-130-1-SS/DICOM”

'Traceback (most recent call last):

Any help would help me.


Looks like you don’t have pybids installed. How did you install bidskit?

I followed this below link to install bidskit.

Is it necessary to install pybids?

Also I tried to run the docker version of fmriprep:
docker run --rm -v $home/naren123/Desktop/TO_BIDS:/sub-01:ro -v $home/naren123/Desktop/TO_BIDS:/output -w /scratch poldracklab/fmriprep:latest /sub-01 /output/out participant -w /out/work/ --ignore fieldmaps

And the terminal output is here:

1: [ERR] Quick validation failed - the general folder structure does not resemble a BIDS dataset. Have you chosen the right folder (with “sub-*/” subfolders)? Check for structural/naming issues and presence of at least one subject. (code: 61 - QUICK_VALIDATION_FAILED)

Please visit for existing conversations about this issue.

Making sure the input data is BIDS compliant (warnings can be ignored in most cases).

It looks like bidskit has imported pybids since, but it’s not in their install_requires. You could open a pull request to add it here:

Then the bidskit installation will automatically install pybids in the process.
