OverflowError: unsigned integer not in range(0, 64), got 64

[Jeanbouvatt]

I got this message when trying to encode values :

values = [-0.39263690585168304, -0.39263690585168304, -0.39263690585168304, 0.450762617155903, 0.450762617155903, 0.450762617155903, -0.284155454538896]
values_encoder = gc.ValuesEncoder()
for v in values:
    print(v)
    values_encoder.encode_next(v)

This output :

-0.39263690585168304

Version 0.0.1

same problem with encode_all

Hi @Jeanbouvatt

Thank you for reporting this. This is happening because I forgot to add the block size adjustment.

I'll fix it and cut a new release.

Thanks again

[ghilesmeddour]

@Jeanbouvatt It's done. Can you please update and confirm that it now works properly for you.

[Jeanbouvatt]

I confirm it now works perfectly, thanks!
