PyRate生成DES模型输入文件遇OSError：文件未找到求助

按照PyRate的DES模型教程生成输入文件时，即使使用绝对路径且文件确实存在，仍触发以下错误：

OSError: 'C:\Users\User\Desktop\PyRate\example_recent.txt' not found.

执行命令及完整报错 #

(base) C:\Users\User\Desktop\\PyRate>python .\PyRateDES.py -fossil 'C:\\Users\\User\\Desktop\\PyRate\\example_fossil.txt' -recent 'C:\\Users\\User\\Desktop\\PyRate\\example_recent.txt' -wd 'C:\\Users\\User\\Desktop\\PyRate' -filename Example -bin_size 0.5 -rep 10 -trim_age 23.03 -taxon accepted_name -area cc -age1 max_ma -age2 min_ma

文件存在性验证 #

已通过glob确认目标文件存在：

import glob

print(glob.glob('C:\\Users\\User\\Desktop\\PyRate\\*.txt'))

runfile('C:/Users/User/.spyder-py3/temp.py', wdir='C:/Users/User/.spyder-py3')
['C:\\Users\\User\\Desktop\\PyRate\\requirements.txt', 'C:\\Users\\User\\Desktop\\PyRate\\example_fossil.txt', 'C:\\Users\\User\\Desktop\\PyRate\\example_recent.txt']

• 移除路径中的单引号：
  Windows命令行不识别单引号作为路径包裹符，单引号会被当作路径的一部分传递给脚本，导致numpy无法定位文件。修改命令为：

  (base) C:\Users\User\Desktop\PyRate>python .\PyRateDES.py -fossil C:\Users\User\Desktop\PyRate\example_fossil.txt -recent C:\Users\User\Desktop\PyRate\example_recent.txt -wd C:\Users\User\Desktop\PyRate -filename Example -bin_size 0.5 -rep 10 -trim_age 23.03 -taxon accepted_name -area cc -age1 max_ma -age2 min_ma
  

  若路径包含空格，推荐用双引号包裹：

  (base) C:\Users\User\Desktop\PyRate>python .\PyRateDES.py -fossil "C:\Users\User\Desktop\PyRate\example_fossil.txt" -recent "C:\Users\User\Desktop\PyRate\example_recent.txt" -wd "C:\Users\User\Desktop\PyRate" -filename Example -bin_size 0.5 -rep 10 -trim_age 23.03 -taxon accepted_name -area cc -age1 max_ma -age2 min_ma
  

• 替换路径分隔符为正斜杠：
  Windows系统中，Python脚本对正斜杠/的兼容性更好，可避免反斜杠的转义问题。修改命令如下：

  (base) C:\Users\User\Desktop\PyRate>python .\PyRateDES.py -fossil "C:/Users/User/Desktop/PyRate/example_fossil.txt" -recent "C:/Users/User/Desktop/PyRate/example_recent.txt" -wd "C:/Users/User/Desktop/PyRate" -filename Example -bin_size 0.5 -rep 10 -trim_age 23.03 -taxon accepted_name -area cc -age1 max_ma -age2 min_ma
  

• 调试脚本的路径接收逻辑：
  若以上方法无效，可临时修改pyrate_lib/lib_utilities.py第503行，添加打印语句确认实际传递的路径：

  print("Target file path:", recent)
  rece = np.genfromtxt(recent, dtype = str, delimiter='\t')
  

  运行脚本后查看输出的路径是否包含多余字符（如残留的单引号），再针对性调整命令行参数。
