I downgraded pip to install some packages. but now pip is not working saying. my python version is 3.11.5 and used this command “sudo python -m pip install pip==18.0 --upgrade”
Error code:

Please, never use sudo python -m pip unless you’re absolutely sure of what you’re doing. It’s a quick way to seriously wreck your environment, possibly beyond repair if you overwrite system packages.
Code and error messages are best shared as text rather than screenshots, so that anyone can read them. I had to squint pretty hard to make out what that image says
You aren’t using Python 3.11 there; you’re using the system Python 3.10 (/usr/bin/python3.10). You appear to have a virtual environment (base) activated, but the pip you called came from your Python 3.10 user site-packages (/home/hasitha/.local/bin/pip).
As you found, pip==18.0 is not compatible with a Python that new. According to the classifiers at on the PyPI page for pip 18.0, the newest version it supported was Python 3.6. Fortunately, since it does appear to be installed to your user site-packages, you should be able to clean things up by removing /home/hasitha/.local/lib/python3.10/site-packages/pip*, and the system-wide pip installation should still work.
I’m not sure how downgrading pip would help you install a package . What was the original issue you were facing; perhaps we can help with that?
Big thank you .I updated the error message with code. It fixed my pip error. I am very sorry about uploading image. Firstly, I was trying to running a model in a virtual machine. For that ‘ctcdecode’ module installation failed. I am not pretty sure but I thought of downgrading pip version may work. That is the cause for the error.
What trouble did you have with installing ctcdecoder? I’m not at all familiar with it, but I found each of ctcdecode, pyctcdecode, and ctcdecoder on PyPI. The latter appears to be a broken and possibly abandoned package (or malware, hard to tell ), the former requires PyTorch to be pre-installed (which is its own can of worms), and the middle installed quickly and easily in a Python 3.11 venv. If you share the error you had with that installation, we can try to help.
Sure, Thank you in advance. I have pytorch preinstalled and It gives a loong error message. I’ll attach it. When i typed “pip install ctcdecode” it gives me error message lastly saying,
