在一段时间后运行我的代码时，PyScripter 打开另一段代码并给出错误消息“EOFError：流已关闭”。
这是代码：
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
import math
from itertools import product, combinations
from numpy import *
fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_aspect("equal")
ra_day = loadtxt("RA Days.txt")
ra_minute = loadtxt("RA Minutes.txt")
ra_second = loadtxt("RA Seconds.txt")
ra = ra_day + (ra_minute/60) + (ra_second/3600)
dec_day = loadtxt("DEC Days.txt")
dec_minute = loadtxt("DEC Minutes.txt")
dec_second = loadtxt("DEC Seconds.txt")
dec = dec_day + (dec_minute/60) + (dec_second/3600)
dist = loadtxt("Distance.txt")
for ra in range(754):
for dec in range(754):
for dist in range(754):
x = math.cos(ra) * (dist * math.cos(dec))
y = math.sin(ra) * (dist * math.cos(dec))
z = dist * math.sin(dec)
ax.scatter([x],[y],[z],color="k",s=100)
ax.scatter([0],[0],[0],color="b",s=100)
plt.show()
请有人帮我解决错误消息。谢谢
