cd h5py
HDF5_DIR=~/Users/bendichter/opt/anaconda3/envs/stream_nwb/ pip install --force-reinstall --no-binary=h5py .


## test out streaming
from pynwb import NWBHDF5IO
from nwbwidgets import nwb2widget
import requests

def get_s3_url(url):
    s3_url = requests.request(url=url, method='head').url
    return s3_url[:s3_url.index('?')]

path = "https://dandiarchive.s3.amazonaws.com/girder-assetstore/58/07/58074d0a5a4a4086afebb4d29912c419"

io = NWBHDF5IO(get_s3_url(url), mode='r', load_namespaces=True, driver='ros3')
nwb = io.read()
nwb2widget(nwb)

you may want to file an issue on conda-forge for hdf5-feedstock, if it is not being compiled on windows with ROS3 VFD support.
