i use sqlite3 database. had models split several files put them in single file no help. tried upgrading flask-migrate, flask-sqlalchemy , other packages no help. wrong?

update: using alembic version 0.6.2

it's odd, few of 0.6.x releases of alembic appear have undefined symbol.

the mistake corrected in release 0.6.7. here commit shows how line corrected: https://github.com/zzzeek/alembic/commit/ead05ce48d40d4235b2395972fd1a6efb96d414c

pretty sure if upgrade 0.6.7 or newer problem resolved.

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
