What that do , please write more comments in your source-code…. 🥱
I really want understand you, I have read parts of repository’s from your git and I ask to U just that:
Why you write an machine learning code, that it’s interest or just publication of result to exercice from an stude for school or also it’s an activity of your free-time ?
You are at the begin of programming practice or U have just an sequential vision of the code you type…. ???
I Can type an document with this contents: 😃
So…
I have so many question just I don’t want know U, a lot of coder’s on that don’t write an user readme, my account it’s for the historical share of all projects I start and want done at the end of this human life I have… 🛩️ So I explore git it’s better for get a lot of free new code,ideas,parts,subs,librabry…. to made my pheonetic-based of an offline Vocal Assistant … My ML/DL research subject I have found today…
