python - 显示无法与 pyvirtualdisplay : "XStartTimeoutError: Failed to start X on display ":100 1"(xdpyinfo check failed)" 一起使用

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();

但是当我尝试运行上述程序时，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是 Why am I getting this message from xauth: “timeout in locking authority file /home//.Xauthority”?

这并不是我在这里真正面对的。我该如何解决这个问题？

我遇到过同样的问题。然后我安装并启动XQuartz这个问题得到了解决。
