It seem to v0.7.1 the new error msg, is that mean my dataset have problem?

And i found the value of “err” is “None”.

Please use the v0.7.1 of generate_package.py, matching the version of ds_ctcdecoder you have installed. It looks like you’re running from a more recent master.

Using v0.7.1 should fix this, but there is also a bug in the decoder binding, thanks for reporting.
