psychopy download troubleshoot in ubuntu

On a very bright sunny day, I decided to download the psychopy software to create some  psychology tests on python. But as soon as I did that, I couldn't open the same. I will discuss in this very small post, how I solved that issue.

First, I downloaded 2020.1.3. version  using the tar file download process explained in the official site. But that didn't work out. Neither the app would open nor it would show any error message in the terminal.

Then my instructor said that he is using 2020.2.4 version in mac. Having that information, I first uninstalled the 1.3. version and then wrote 

pip3 install psychopy==2020.2.4

Now, I got a error in my terminal saying something like:

ImportError: libwebkitgtk-3.0.so.0: cannot open shared object file: No such file or directory

Now on searching this in google, you will see that this is a psychopy github issue. Which basically tells you to install the libwebkitgtk of the said version. So you have to type:

sudo apt-get install libwebkitgtk-3.0-0

and this downloads the proper file.

Now I thought that my woes are over and went ahead and called psychopy again from the terminal. Now, the app opens up to some level, then a written error comes up, saying that 

ImportError: libSDL-1.2.so.0: cannot open shared object file: No such file or directory

 

So you go ahead and type according to this issue about this error:

sudo apt-get install libsdl1.2debian

Finally after successfully installing this library, psychopy opens up properly and runs. There are still some warnings about pixman and some other libraries, as well as some shape checks; but overall it is fine now. 

So if you were stuck downloading psychopy, I hope you got helped!

Mastering SQL for Data Science: Top SQL Interview Questions by Experience Level

Introduction: SQL (Structured Query Language) is a cornerstone of data manipulation and querying in data science. SQL technical rounds are designed to assess a candidate’s ability to work with databases, retrieve, and manipulate data efficiently. This guide provides a comprehensive list of SQL interview questions segmented by experience level—beginner, intermediate, and experienced. For each level, you'll find key questions designed to evaluate the candidate’s proficiency in SQL and their ability to solve data-related problems. The difficulty increases as the experience level rises, and the final section will guide you on how to prepare effectively for these rounds. Beginner (0-2 Years of Experience) At this stage, candidates are expected to know the basics of SQL, common commands, and elementary data manipulation. What is SQL? Explain its importance in data science. Hint: Think about querying, relational databases, and data manipulation. What is the difference between WHERE ...

Spacy errors and their solutions

 Introduction: There are a bunch of errors in spacy, which never makes sense until you get to the depth of it. In this post, we will analyze the attribute error E046 and why it occurs. (1) AttributeError: [E046] Can't retrieve unregistered extension attribute 'tag_name'. Did you forget to call the set_extension method? Let's first understand what the error means on superficial level. There is a tag_name extension in your code. i.e. from a doc object, probably you are calling doc._.tag_name. But spacy suggests to you that probably you forgot to call the set_extension method. So what to do from here? The problem in hand is that your extension is not created where it should have been created. Now in general this means that your pipeline is incorrect at some level.  So how should you solve it? Look into the pipeline of your spacy language object. Chances are that the pipeline component which creates the extension is not included in the pipeline. To check the pipe eleme...
