QUESTION
I followed a tutorial online and used OLS to build the model (from statsmodel!) The OLS analysis result gave me an amazing R^2 value (0.909). However, when I tried using the r2_score function by scikit-learn to evaluate the R^2 score, I only got 0.68.
Can someone tell what the difference is here?
The dataset came from here: https://www.kaggle.com/harlfoxem/housesalesprediction
Attached is my code!
...ANSWER
Answered 2022-Mar-18 at 07:19Your R2=0.909 is from the OLS on the train data, while the R2_score=0.68 is based on the correlation of the test data.
Try predicting the train data and use R2_score on the train and predicted train data.
QUESTION
Our Self-hosted GitLab server is randomly getting broken and we couldn't figure out why. This random behavior affects our deployments, it gets too slow. After restarting it, stays up for a few hours and goes down, throws 500 or 502 error. After bringing it back up, I see either the sidekiq or gitaly metrics on omnibus grafana dashboard goes down compared to other services. What do these services do and how to debug this issue?

ANSWER
Answered 2022-Mar-15 at 10:05I've met the same kind of issue after a few months not using an instance i had setup for one of my customers. You might want to check that your instance is up to date and update it if not - some vulnerabilities might be at fault here.
In my case it was a weird process sucking all my cpu, i suspect some kind of crypto currency miner was ran using a known exploit that was fixed in a later update, all went better after i killed it and updated the version.

QUESTION
I am trying to create an app that records the device's screen and displays it to an ImageView frame by frame. So far I have only implemented a screen recorder sourced from this link. When the recording is stopped it is saved to a file. Instead of saving the recording to a file, I wish to retrieve each frame and display to an ImageView. Using the MediaRecorder API, is there any way to do this?
RecordingSession.java
...ANSWER
Answered 2022-Jan-09 at 17:31You wouldn't do an ImageView for this. You'd use a SurfaceView. It's meant to be used for things like media playback. https://developer.android.com/reference/android/view/SurfaceView?hl=en
You can find a bunch of examples on how to use it on Google, such as https://gist.github.com/scottgwald/7743453

QUESTION
hellow every one i migrated gitlab-ce into a new instance with new domain name using backup/restore
my problem : when i click a project it gives me "500 Whoops, something went wrong on our end "
i installed the same gitlab-ce version in the new host which is 13.6.2
my gitlab status
...ANSWER
Answered 2021-Oct-28 at 16:29To fix this problem I had to migrate gitlab-secrets.json
from /etc/gitlab
too, because this file contains the database encryption key, CI/CD variables, and variables used for two-factor authentication.
If you fail to restore this encryption key file along with the application data backup, users with two-factor authentication enabled and GitLab Runner lose access to your GitLab server.
QUESTION
After setting up a GitLab server, GitLab runner CI, and creating a test-repository that completes a CI-job successfully, I was experiencing some difficulties in ensuring a post-receive
script is completed after the CI is finished successfully on the test repository commit.
The MWE does the complete deployment, and uploads a repository to the GitLab server and runs the CI on the repository. However, it is not yet generalised well, hence it has (at least) the following requirements: System: Ubuntu 20.04, Architecture:AMD64.
...ANSWER
Answered 2021-Oct-09 at 17:47The issue was that I was twofold:
- I created the
post-receive
script inside the linux user, instead of inside the docker. - I was looking for the output of the
post-receive
script in the wrong location. I assumed that it would produce an output in the same directory as the script is located. But thepost-receive
script is called from the root of the.git
directy, hence that is where the output is created.
Initially I tried to overcome the issue of 2 by using an absolute path, but issue 1 implied that the absolute path that I had chosen did not actually exist inside the Docker container. Therefore, no output was created, (and I was looking in the wrong place for that output on the Linux device, instead of in the Docker container).
The manual solution I found was:
First get the Docker container id with: sudo docker ps -a
, which returned ... ca3ba74eb832 ...
. Then open the docker inside the terminal with:
QUESTION
ABC is a music notation; I'm working on patterns to parse it as part of an app.
Sometimes multiple renditions of a tune are in an ABC file, and I need to get just the first rendition -- or in an ideal world any rendition I specify. The beginning of a rendition is signified by the X: string.
It's not possible to know in advance how many renditions are in a file.
In Javascript, how can I return, for example, the first rendition (from the first X: inclusive to the beginning of the second) in the example below, in a way that will return the first if there is no second, and return the first if there are more than two renditions.
My work so far yields ([\s\S]*)(?=X:)
which succeeds in the two rendition example, but fails with a single rendition or more than two.
Adding an 'OR'd end of file condition to the lookahead lets the single rendition case work, but fails on the one and three rendition cases, e.g. \([\s\S]*)(?=X:|$)
Any help appreciated ... a good way to parse ABC will be used by many.
A two-rendition example can look like the below -- for a three rendition example just add a line with X: at the end, and for a single chop off everything from the second X:
EDITS: Folks have been kind enough to ask for better examples, and they won't fit in a comment, so here's a few
Broken pledge is interesting because it has more than one ABC and they're not numbered sequentially:
...ANSWER
Answered 2021-Sep-19 at 17:19This is a complete rewrite of the answer, sorry. The following function returns the info you are currently interested in (it can be extended to return more info, like, e.g., the titles of the renditions as an array sharing indices with the renditions
array).
QUESTION
I change GitLab docker image to latest version but after run, service doesn't start and just log this, What should I do?
...ANSWER
Answered 2021-Sep-06 at 16:56The answer is already in your post:
It seems you are upgrading from major version 13 to major version 14. It is required to upgrade to the latest 14.0.x version first before proceeding. Please follow the upgrade documentation at https://docs.gitlab.com/ee/update/index.html#upgrading-to-a-new-major-version
This gives more information.
Ideally, you should:
- take a backup of your data folder
- upgrade to
13.12.11-ce
(the last minor of your current major release) - upgrade to
14.0.10-ce
(the first minor of the new major release) - upgrade to
14.2.3-ce
(your target, i.e. the last minor of the new major release)
