Which pynwb version are you using?

[melancholy12]

@t-b Thanks for your reply. My version of pynwb is 1.5.1

My version of pynwb is 1.5.1.

That is a version which should work. Are you sure you are using the recommended hdmf/h5py versions for this particular pynwb version? This old pynwb version requires h5py < 3.0, see https://github.com/hdmf-dev/hdmf/blob/dev/CHANGELOG.md#hdmf-300-july-6-2021.

The easiest thing is probably to use the latest pynwb version (2.3.2, see https://github.com/NeurodataWithoutBorders/pynwb/releases/tag/2.3.2).
