module 'statsmodels.formula.api' has no attribute 'OLS'

In some version of 'statsmodels' OLS is directly available in statsmodels.api. So we don't have to use 'statsmodels.formula.api', instead of it, we can use 'statsmodels.api'. So final syntax would be like-
Code:-
import statsmodels.formula.api as sm
model_ols = sm.OLS(endog=y, exog=X).fit()
Output:-
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-2-39f3885d5ce0> in <module>
----> 1 model_ols = sm.OLS(endog=y, exog=X).fit()

AttributeError: module 'statsmodels.formula.api' has no attribute 'OLS'

How we can fix:-
import statsmodels.api as sm
model_ols = sm.OLS(endog=y, exog=X).fit()
model_ols.summary()
Output:-

Failed to get D-Bus connection: Operation not permitted

" Failed to get D-Bus connection: Operation not permitted " - systemctl command is not working in Docker container. If systemctl command is not working in your container and giving subjected error message then simple solution of this error is, create container with -- privileged option and also provide init file full path  /usr/sbin/init [root@server109 ~]# docker container run -dit --privileged --name systemctl_not_working_centos1 centos:7 /usr/sbin/init For detailed explanation and understanding I am writing more about it, please have look below. If we have a daemon based program(httpd, sshd, jenkins, docker etc.) running inside a container and we would like to start/stop or check status of daemon inside docker then it becomes difficult for us to perform such operations , because by default systemctl and service  commands don't work inside docker. Normally we run below commands to check services status in Linux systems. [root@server109 ~]# systemctl status

AWS cloud automation using Terraform

In this post I'll create multiple resources in AWS cloud using Terraform . Terraform is an infrastructure as code( IAC ) software which can do lots of things but it is superb in cloud automation. To use Terraform we have write code in a high-level configuration language known as Hashicorp Configuration Language , optionally we can write code in JSON as well. I'll create below service using Terraform- 1. Create the key-pair and security group which allow inbound traffic on port 80 and 22 2. Launch EC2 instance. 3. To create EC2 instance use same key and security group which created in step 1 4. Launch Volume(EBS) and mount this volume into /var/www/html directory 5. Upload index.php file and an image on GitHub repository 6. Clone GitHub repository into /var/www/html 7. Create S3 bucket, copy images from GitHub repo into it and set permission to public readable 8 Create a CloudFront use S3 bucket(which contains images) and use the CloudFront URL to update code in /var/w
