Error with requirements.txt

[belguutei]

Hello,

I was trying to follow along your tutorial, but when I ran the command "pip install -r requirements.txt" I got this error:
ERROR: Could not find a version that satisfies the requirement torch==1.8.1+cu111 (from versions: 2.0.0, 2.0.1, 2.1.0, 2.1.1, 2.1.2, 2.2.0)
ERROR: No matching distribution found for torch==1.8.1+cu111

I don't have much experience with coding since I studied math in school.
Please help me

This is a common issue when specific versions are packaged with CUDA support in the requirements.txt file. To resolve this, you'll need to install PyTorch directly from the official PyTorch website. Please follow these steps:

1. If you're using a virtual environment (highly recommended to avoid conflicts between projects), activate it with one of these commands:

   • On macOS/Linux: source <env-name>/bin/activate
   • On Windows: <env-name>\Scripts\activate
     Replace <env-name> with the name of your virtual environment. Using a virtual environment helps isolate and manage project dependencies.

2. Install Other Requirements: Remove any PyTorch related lines (torch, torchvision, torchaudio) from your requirements.txt file, then install the remaining requirements: pip install -r requirements.txt

3. Install PyTorch:

   • If you're using a GPU, run the following command (adjust the CUDA version if needed).
     pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

   • For CPU-only installations, use
     pip install torch torchvision torchaudio

You can find the command that matches your operating system and CUDA version on the PyTorch installation page: https://pytorch.org/
