Errors coming up: run, pip install -r requirements

[Mremenar]

Hi.

Getting a couple of errors, that may be caused by where I installed to. I created an "AI" directory at root (C:/AI) and installed your software there. Followed all install instructions. I have Python 3.12 installed already. When I run VS Code, I get:

                           File "c:/AI/QualityScaler-main/QualityScaler.py", line 270

                             match self.directml_gpu:

                                      ^

                         SyntaxError: invalid syntax

When I run pip install -r requirements.txt

                         [notice] A new release of pip is available: 24.3.1 -> 25.2
                         [notice] To update, run: python.exe -m pip install --upgrade pip
                         ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

Requirements.txt is located in at C:\AI\QualityScaler-main

I'm running an MSI Aegis R2, I9-14900F (32 CPUs) ~2GHz, 65536MB RAM with RTX 4080 Super on Windows 11 Home 34 Bit 10.0 Build 26100
Not sure what I'm doing incorrectly, so thank you in advance your help in resolving this.

Hi my friend,

the problem is that you did not install requirements.txt correctly.
ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

You must point the vscode terminal to the QualityScaler folder with the command cd /folder/

For example, if you download requirements.txt on Desktop you should do:

cd .\Desktop\
pip install -r requirements.txt

but it all depends of the directory you actually are with terminal

OR

you can just use
pip install *name_of_the_library*

for each library in the file requirements.txt, like

pip install onnxruntime-directml==1.22.0
pip install numpy

.
.
and so on

I still get the error.  For some reason it is trying to load Python 3.7 instead of 3.12.  There is no 3.7 in my environment variables, nor does it show in my installed apps/programs.I do have PyCharm, I will try removing it and rebooting.

Hi my friend, i see that you are using pyenv environments.

Some libraries are not supported in pyenvs, you should use python native on PC following the guide
https://github.com/Djdefrag/QualityScaler?tab=readme-ov-file#make-it-work-by-yourself-%E2%80%8D

I uninstalled PyEnv, reran the requirements, rebooted and tried the play button on QualityScaler.py and got this: PS C:\Users\tomah> pyenv shell 3.12.8 pyenv : The term 'pyenv' is not recognized as the name of a cmdlet, function, script file, or operable program.

Hi my friend,

you unistalled pyenv but your IDE is still pointing to that as Python executable, somewhere in your IDE you can change that setting.

I reccomend to use VSCode because is quite simple to use

nice, so at the bottom right you can change this setting clicking on "Python x.x.x"

Thank you for your help and patience, it finally loads. Do you have any final recommendations for improving video quality (removing granularity, increasing sharpness)?  I updated the VRAM settings for my card (16GB for the 4080 Super), is there a better AI model than the default (RealESR Gx4)?

I tried improving the video quality of a video clip using two different models: RealESR_Gx4_InputR-50_OutputR-100_Blending-Low
and
RealESRGANx4_InputR-50_OutputR-100_Blending-High (I added the 8 AI threads to this one).

Several hours later, neither of these seemed to actually do anything to improve the video quality. Both of them reduced the size of the video in half--from 1.3 GB to 616 and 617 MB, respectively. But the video (an 8 minute clip from a 1990s TV show recorded by VCR) showed no improvement in quality.

Any ideas on how I can achieve this improvement?
