显示器与 pyvirtualdisplay 不兼容："XStartTimeoutError: Failed to start X on display "：1001 " (xdpyinfo check

Question

我正在使用macOS Mojave并尝试运行以下内容：

import torch
import torch.nn as nn
import torch.nn.functional as F 
from torch import optim
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
from pyvirtualdisplay import Display
from IPython import display as ipythondisplay
from IPython.display import clear_output
from pathlib import Path
import random, os.path, math, glob, csv, base64, itertools, sys
import gym
from gym.wrappers import Monitor
from pprint import pprint
# The following code is will be used to visualize the environments.
def show_video(directory):
html = []
for mp4 in Path(directory).glob("*.mp4"):
video_b64 = base64.b64encode(mp4.read_bytes())
html.append('''<video alt="{}" autoplay 
loop controls style="height: 400px;">
<source src="data:video/mp4;base64,{}" type="video/mp4" />
</video>'''.format(mp4, video_b64.decode('ascii')))
ipythondisplay.display(ipythondisplay.HTML(data="<br>".join(html)))
display = Display(visible=0, size=(1400, 900))
display.start();

但是当我尝试运行上述内容时，出现以下错误：

---------------------------------------------------------------------------
XStartTimeoutError                        Traceback (most recent call last)
<ipython-input-1-73a977c6bd7e> in <module>
31 
32 display = Display(visible=0, size=(1400, 900))
---> 33 display.start();
34 
35 def make_seed(seed):
/usr/local/lib/python3.7/site-packages/pyvirtualdisplay/abstractdisplay.py in start(self)
166         if not ok:
167             msg = 'Failed to start X on display "%s" (xdpyinfo check failed).'
--> 168             raise XStartTimeoutError(msg % d)
169         return self
170 
XStartTimeoutError: Failed to start X on display ":1001" (xdpyinfo check failed).

我得到的唯一接近的事情是为什么我从 xauth 收到这条消息："锁定权限文件/home//超时。Xauthority"？

这不是我在这里真正面对的。如何解决此问题？

我遇到了同样的问题。然后我安装并启动了XQuartz这个问题得到了解决。
