If the folder is already on your path, then double check that the filename is spelled correctly. Is the actual file extension JPG or jpeg?
Are you on a Linux system?

imds = imageDatastore('C:\Users\new\Testing',...
'IncludeSubfolders',true,...
'LabelSource','foldernames');
The data store includes subfolders
inp = input('Enter input :');
I = imread(inp);
What is being entered is a plain file name, relative to the current directory . It is not going to be looked for under C:\Users\new\Testing -- and if it were to be looked for there, there would be the problem that files by the same name might exist in any of several different subdirectories of C:\Users\new\Testing
The user needs to enter a filename that exists in the current directory, or the user needs to enter a fully-qualified filename.
Alternately, it is possible to search the imds for the file... though there is the risk that the file appears multiple times.

Replace
inp = input('Enter input :');
with
[filename, pathname] = uigetfile('*.*', 'Select a file');
if isnumeric(filename)
error('User canceled file selection');
end
inp = fullfile(pathname, filename);

You can add the path to the directory where your images are located using addpath(), e.g.:
addpath('C:\Users\new\Testing')

can u tell me at which line i dont have spaces so i can gt more clarity
testing is my folder and i have images in them and they i dont have any spaces if their i have to change tell me how to do.
if it is in the code pl mention me the line so i can be easy to understand for me

It's not on any line. It was manually entered via an interactive prompt. This is an example of why using interactive prompts is a great way to collect typos that often leave no lasting evidence when you have to go back and figure out where a bug originated. The only reason I noticed this is because the error message indicates what was entered at the prompt.
