Ошибка при установке TorchVision

В настоящее время я пытаюсь запустить PyTorch, но у меня постоянно возникают проблемы.

Установка факела прошла хорошо, но при попытке установить torchvision я сначала столкнулся со следующей проблемой:

    Exception:

  File "/usr/lib/python3.6/json/encoder.py", line 257, in iterencode
    return _iterencode(o, 0)
MemoryError

Затем я попробовал это снова, но на этот раз с добавленным –no-cache-dir.

Я столкнулся со следующим исключением:

During handling of the above exception, another exception occurred:

Кто-нибудь знает, в чем проблема?
