Tensorflow проблемы установки GPU

Я попытался установить поток тензора в своей системе, и я подвергаюсь следующей ошибке

" Exception:

Я изменил полномочия своей папки Python 2.7, но тем не менее я получаю ту же ошибку во время установки.

Любезно сообщите мне о проблеме в моем процессе установки.
