Retrying with flexible solve. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. PackagesNotFoundError: The following packages are not available from current channels: - cpuonly - pytorch==1.8.0 - torchvision==0.9.0 - torchaudio==0.8.0

It seems that you are encountering some issues with installing the required packages for PyTorch. The error message suggests that the packages you are trying to install are not available from the current channels.

To resolve this issue, you can try the following steps:

1. Create a new conda environment:

conda create -n myenv python=3.8

2. Activate the new environment:

conda activate myenv

3. Install PyTorch and torchvision using conda:

conda install pytorch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 cpuonly -c pytorch

By specifying the `-c pytorch` flag, conda will search for the packages in the PyTorch channel.

Please note that the `cpuonly` variant installs PyTorch without CUDA support, which means it will not utilize GPU acceleration. If you have a compatible GPU and want to enable GPU acceleration, you should install the appropriate version of PyTorch with CUDA support.

I hope this helps! Let me know if you have any further questions.
