What is the reason for this?

print:

The remoteApi library could not be loaded. Make sure
it is located in the same folder as "vrep.py", or
appropriately adjust the file "vrep.py"

But they locate in the same fiolder.

I have solved this problem. I think the operating system you have used is windows and the python file in it needs a remote API file to run. So I recommend you copy the remoteApi.dll file to the simulation folder.

Where can I get these two files which you mentioned?
Thanks in advance :)

These two files are contained in the location where the software CoppeliaSim is installed. Exactly, CoppeliaSim/programming/remoteApiBindings/lib/lib/. I can not guarantee the difference between the PC.
Hope this will help you.

Hello, I found the remoteApi.dll file but did not find the simulation folder. Could you please help me whether the simulation folder is in the repository or somewhere else?

Many thanks for your time and help
