Is there any solution to this problem?

This closed solution doesn't work for me.

After the version was updated, there was still the same problem, and #27 didn't help 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.

I followed the above the suggestions, and it solved 'Cannot connect sqlite3...' error but produced another runtime error on the same line:

self._metadata_store = metadata_store_serialized.CreateMetadataStore(
RuntimeError: Error when executing query: file is not a database query: CREATE TABLE IF NOT EXISTS Type ( id INTEGER PRIMARY KEY AUTOINCREMENT, name VARCHAR(255) NOT NULL, version VARCHAR(255), type_kind TINYINT(1) NOT NULL, description TEXT, input_type TEXT, output_type TEXT );
