TypeError of import nibabel will be displayed after running make html

[lincong8722]

When I use sphinx for document generation, run make html after quoting the function, and an error of nibabel will be displayed, as follows:

WARNING: autodoc: failed to import module 'node' from module 'src.interface'; the following exception was raised:

I am using nibabel ==3.2.2 When I run node.py alone, it can run, but once I use sphinx to generate the document, I will report an error. I don't know where the problem is. How can I solve this error?
