I wrote a small script to check whether a text file exists in a folder. I have created a folder named depth_estimation and it contains a file named K.txt (Attaching screenshot for reference). While I try to read the text file it throws an error stating the file is not found but when I checked the folder the file actually exists. I am just a beginner!
