I got this working on windows by downloading: the sqlite3 dll (find your system version)
And placing it into the folder: C:\Users\YOURUSER\Anaconda3\DLLs
(Depending on how you installed Anaconda, this may have to be placed into
the following folder: C:\ProgramData\Anaconda3\DLLs
)
According to @alireza-taghdisian, you can locate the exact path of
your conda environments (where you need to copy the sqlite3 dll) by typing:
conda info --envs
on your anaconda prompt.
