QUESTION
A table1 contains a list of ids. The goal is to check if inside a table3 (for each id from the table1) there is a row which contains this id. If not, I would like to insert a new row which contains a list of values.
I've tried to do it with this block:

QUESTION
I’m getting auto generated IDs in my firestore collection even though I’m specifying IDs when creating documents.
I am currently load testing my FastAPI app, currently testing it synchronously. My firestore IDs are coming from a counter stored in firebase’s realtime DB. The counter consists of alphanumeric characters and I’m incrementing them in a transaction. I’m then seeing if a document with that ID exists in firestore, when I find a ID that doesn’t exist I use .set() to create a document with that ID.
...ANSWER
Answered 2022-Feb-05 at 14:33Figured out that increment_realtimedb() was returning None somehow. I changed the while loop to check if new_id was None. That seems to have fixed the problem.

I'm trying to connect my go app to a heroku redis db. With this code:

...ANSWER
Answered 2022-Jan-10 at 14:00Try by doing RDB
persistence off. If you still get the same error it means there is issue with Heroku.
RDB needs to fork() often in order to persist on disk using a child process. Fork() can be time consuming if the dataset is big, and may result in Redis to stop serving clients for some millisecond or even for one second if the dataset is very big and the CPU performance not great.
For better understanding refer this link : https://redis.io/topics/persistence
Make sure, you create one instance for connection and use it everywhere, it is thread safe.
Also make sure :
TCP keepalive is enable -> It will prevent unexpected connection closed events.
You can refer this link : https://redis.io/topics/clients
Increase the opt.MaxRetries

First of all I am sorry for my newbie question, but I am kinda stuck here. Could anyone please tell me step by step how to use Redis in my Rails 6 application, if I have Windows OS? I have installed Redis, currently it is in my C:\Program Files, with these files inside it

...ANSWER
Answered 2021-Dec-02 at 15:57You are using a very old and deprecated version of Redis, an abandoned project by Microsoft called OpenTech Redis.
I suggest you checkout Memurai. Memurai is an up-to-date native Windows port of Redis that derives from that project (see this commit).
Memurai is also available with a free Developer Edition.

QUESTION
Problem: I'm receiving a FOREIGN CONSTRAINT error (code 787) when I try to delete a file stored in a SQLite database. Everything else works with adding (i.e., insert
) the files and even reading (opening) them. I just can't delete them.
What I have tried: I've read 4-5 posts calling it a known issue. I think one post involved a type of conflict. A type conflict might be a possibility except I can insert
and read (open) just fine. I don't think that is the issue in my case... maybe, but I'm not sure. Before going that far I thought I would post here. I'm still learning about Android Room and Android in general, but could use some insights by those more learned than me.
Where the error occurs
...ANSWER
Answered 2021-Nov-23 at 16:20With the help and comments of Susan Mustafa, I simply had my join table dependency in the wrong code order when attempting to delete the file. Once I reversed the order of the code pertaining to the file the Foreign Key
error disappeared. I should have caught this but didn't, the foreign key dependencies should be removed first before removing the primary.
These were in reverse order:
QUESTION
I am using optuna to tune xgboost model's hyperparameters. I find it stuck at trial 2 (trial_id=3) for a long time(244 minutes). But When I look at the SQLite database which records the trial data, I find all the trial 2 (trial_id=3) hyperparameters has been calculated except the mean squared error value of trial 2. And the optuna trial 2 (trial_id=3) seems stuck at that step. I want to know why this happened? And how to fix the issue?
Here is the code
...ANSWER
Answered 2021-Nov-16 at 20:09Although I am not 100% sure, I think I know what happened.
This issue happens because some parameters are not suitable for certain booster type
and the trial will return nan
as result and be stuck at the step - calculating the MSE
score.
To solve the problem, you just need to delete the "booster": "dart"
.
In other words, using "booster": trial.suggest_categorical("booster", ["gbtree", "gblinear"]),
rather than "booster": trial.suggest_categorical("booster", ["gbtree", "gblinear", "dart"]),
can solve the problem.
I got the idea when I tuned my LightGBMRegressor Model. I found many trials fail because these trials returned nan
and they all used the same "boosting_type"="rf"
. So I deleted the rf
and all 100 trials were completed without any error. Then I looked for the XGBRegressor
issue which I posted above. I found all the trials which were stuck had the same "booster":"dart"
either. So I deleted the dart
, and the XGBRegressor
run normally.
