Olá, alguém pode me ajudar, por favor? Recebi uma tela preta após instalar os drivers nvidia cuda.
UBUNTU 20.04, kernel 5.8.0-55-genérico
Versão do driver NVIDIA-SMI 465.27 : 465.27
Versão CUDA: 11.3
20 GB de RAM, 2 GB Nvidia MX150, Intel Core i7-8550U.
Também estou recebendo esta mensagem ao tentar executar um modelo: "RuntimeError: CUDA sem memória. Tentei alocar 20,00 MiB (GPU 0; 1,96 GiB de capacidade total; 2,00 MiB já alocados; 9,50 MiB livres; 4,00 MiB reservados no total por PyTorch) "
