libcrypto-1_1-x64.dll
libssl-1_1-x64.dll
and paste to anaconda3>DLLs.
then restart your pc.

[torch 설치] Solving environment: failed with initial frozen solve. Retrying with flexible solve
답글삭제1. 위 lib들을 conda로 먼저 설치 후, torch를 conda로 설치 시에 발생
2. 이후에 conda로 설치하는 lib는 계속 이와 같은 오류 발생
3. 해결책으로 먼저 torch를 설치하는데, pip명령으로 먼저 설치.
pip install torch==1.12.1+cu116 torchvision==0.13.1+cu116 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu116
그 다음, conda로 git, jupyter, ...등을 차례로 설치함.
