Nvidia - Erro de dígitos: Gdk-CRITICAL **: gdk_cursor_new_for_display

Question

No servidor amazon g2.2xlarge executando o ubuntu 14.04 Eu tentei instalar os dígitos da Nvidia. (depois de instalar cuda, cudnn e caffe com sucesso)

Mas, quando tento executar o arquivo 'runme.sh' no diretório Digits-2.0, encontro o seguinte erro:

libdc1394 error: Failed to initialize libdc1394 PuTTY X11 proxy: unable to connect to forwarded X server: Network error: Connection refused

** (digits-devserver:12172): WARNING **: Could not open X display PuTTY X11 proxy: unable to connect to forwarded X server: Network error: Connection refused PuTTY X11 proxy: unable to connect to forwarded X server: Network error: Connection refused

Como posso corrigir esse erro?

    

Answer 1

Minha abordagem é menos que ideal, mas funciona.

Editar: {caffe_root}/python/caffe/__init__.py

Adicione as seguintes linhas ao topo:

import matplotlib
matplotlib.use('Agg')
