(pytorch) D:\Python\PythonCharm\STUDY_CNN>conda install opencv-python Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Collecting package metadata (repodata.json

It seems like the installation of the package opencv-python has failed. The error message indicates that the initial frozen solve has failed and the environment is retrying with a flexible solve. This can happen when there are conflicting dependencies or when the package repository is not up-to-date.

You can try updating the conda package repository by running the following command:

conda update conda

Then, try installing the opencv-python package again using the following command:

conda install opencv-python

If the issue persists, you can try creating a new conda environment and installing the package in that environment.

在尝试收集包元数据时出现了错误。具体来说，连接到地址为https://conda.anaconda.org/pytorch/win-64/current_repodata.json的链接失败了。可能是由于网络连接问题，导致HTTP请求失败。可以尝试重新连接，因为HTTP错误往往是间歇性的。

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.
