"No space left on device" et "You don't have enough free space in /var/cache/apt/archives/".

J'utilise un conteneur docker ubuntu 18.04. Je suis confronté à une erreur de manque d'espace.

$ cat /etc/lsb-release

Lorsque j'essaie d'entraîner un modèle resnext101 à partir de torchvision, j'obtiens l'erreur suivante.

Quand je cours df J'obtiens ceci, un de mes tmpfs ne fait que 65 mb. J'ai essayé de lancer export TMPDIR=/var/tmp y export TMPDIR=~/Data/tmp

$ df

Mais l'erreur est toujours présente.

Lorsque j'essaie de mettre à jour des paquets, j'obtiens une autre erreur : E: You don't have enough free space in /var/cache/apt/archives/.

Quand je cours, sudo du -hsc /var/cache

1.6M    /var/cache
1.6M    total

Il y a très peu de place dans mon /var/cache.

J'ai essayé clean , autoclean , clean packages , lien symbolique sudo ln -s /home/apt/ /var/cache/apt mais ces erreurs persistent.
