加载pickle文件时，即使文件存在，也会返回“找不到带名称的文件”(file_name

import os

file_path = 'path/to/your/file.pkl'
if not os.path.exists(file_path):
    print(f"文件 {file_path} 不存在")
else:
    with open(file_path, 'rb') as f:
        data = pickle.load(f)

file_path = 'path/to/your/file.pkl'
if not os.path.exists(file_path):
    print(f"文件 {file_path} 不存在")
else:
    with open(file_path, 'rb') as f:
        data = pickle.load(f)

import os

file_path = os.path.abspath('path/to/your/file.pkl')
if not os.path.exists(file_path):
    print(f"文件 {file_path} 不存在")
else:
    with open(file_path, 'rb') as f:
        data = pickle.load(f)

import os

file_path = 'path/to/your/file.pkl'
if not os.access(file_path, os.R_OK):
    print(f"文件 {file_path} 没有读取权限")
else:
    with open(file_path, 'rb') as f:
        data = pickle.load(f)
