RuntimeError: Cannot connect sqlite3 database: unable to open database file

[Raketenpete]

To get started, I just ran the example code. Unfortunately I get a RuntimeError. Did anyone get the same error or has an idea to solve it?
Thanks in advance!

EDIT1: Formating
EDIT2: Changed VENV from python 3.7 to python 3.8 but didn't solve the problem

This one worked for me:

I found the problem and solved it.
I made directory name like "c:/tmp/filedb-352355"
352355 is random value from 0 to 1000000. (We can find this code in ml_metadata_db.py line 102)

Running started... I wish this tips is helpful.

This with

`# Addresses `UnrecognizedFlagError: Unknown command line flag 'f'`
sys.argv = sys.argv[:1]
# `app.run` calls `sys.exit`
try:
    app.run(lambda argv: None)
except:
    pass`

between import and trainer =.... solved it for me!

Thanks @aprikyan !!
