Hello,

Could you provide a file showing the problem so that I can try to find the issue ?

File Load Error for etf.hdf5
etf.hdf5 is not UTF-8 encoded

file: "etf.hdf5"
import pandas as pd
d = {'col1': [1, 2], 'col2': [3, 4]}
df = pd.DataFrame(data=d)
df.to_hdf('etf.hdf5', key="etf", mode='a', complevel=9, complib="blosc")
pd.read_hdf('etf.hdf5','etf')

Yes, it doesn't work when opening the file this way. Try to double click on it in the file browser.

Note also that you need to install hdf5plugin if you use blosc to compress your datasets.
