显示器无法与pyvirtualdisplay配合使用：“ XStartTimeoutError：无法在显示器”：1001”上启动X（xdpyinfo检查失败）”

Question

我正在使用macOS Mojave并尝试运行以下命令：

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();

但是当我尝试运行以上命令时，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东西是Why am I getting this message from xauth: “timeout in locking authority file /home//.Xauthority”?

这不是我在这里真正面对的。如何解决此问题？

我有同样的问题。然后我安装并开始XQuartz，此问题已解决。
