There's a typo in your code, in the mysql connect method you are passing in "datebase" instead of "database" as an argument.

Cannot connect to MySQL database in TensorFlow Extended

I am having problems using a MySQL database as a metadata database in a TensorFlow Extended pipeline.
I used the penguin template to set up a very simple pipeline and also set up a MySQL database locally.
The only thing I changed in the code was using
tfx.orchestration.metadata.mysql_metadata_connection_config as the metadata_connection_config input to the pipeline instead of tfx.orchestration.metadata.sqlite_metadata_connection_config
from tfx import v1 as tfx
# [...] Add a simple CsvExampleGen
tfx.dsl.Pipeline(
pipeline_name=pipeline_name,
pipeline_root=pipeline_root,
components=components,
metadata_connection_config=tfx.orchestration.metadata
.mysql_metadata_connection_config(
host="localhost",
port=3306,
database="ml_metadata",
username="root",
password="password"),
beam_pipeline_args=beam_pipeline_args,
)
Running this code results in the following error message:

Answer is in probably your post:
Message: 'chromedriver.exe' executable needs to be in PATH
So please try adding chromedriver.exe to your system variable PATH.
For Windows, open System Properties - Environment Variables - and modify System variable "PATH": click Edit, add new entry with path to chromedriver.exe, for example: C:\drivers\chromedriver.exe

I have literally spent days on this, I did not face this issue when i was using the default django database engine, sqlite3.
I have tried doing this:
$python manage.py migrate sites
My SITE_ID setting is set to 1.
I tried removing the 'django.contrib.sites' thing from the INSTALLED_APPS setting, but that throws this error:

Any suggestions would be much appreciated.
Thanks.
uncomment the django.contrib.sites from installed apps
then
python manage.py migrate sites
python manage.py migrate
if you have few table in the database, drop the tables and then run this

anyone happen to see same problem?Could you please give me some suggestion.
all ,nothing wrong with mysql, and Django. It's for I use a complex SQL to access mysql:
SELECT *
FROM
(SELECT *,
#batch_rank := IF(#current_batch = spider , #batch_rank + 1, 1) AS batch_rank,
#current_batch := spider
FROM deja_crawler.crawl_batch_record
where spider in (select distinct spider from deja_crawler.crawl_batch_record where spider like '%_new' or spider like '%_update')
ORDER BY spider, create_time DESC)
ranked
WHERE batch_rank <= 3
the tables used to have not too much data, so it works, later, the table became huge, and the access time cost is almost 30s, but the connection time out is set as 20s, so it will raise time out error.
