PermissionError: [Errno 13] Permission denied: 'trainval.txt'

问题

突然出现了一个让人蒙逼的错误

trainval = open(os.path.join(txtsavepath, '/trainval.txt'), 'w')

好好的一段代码，就是报错：

Traceback (most recent call last): File "/home/zh/local/flowChart/codes/ocr_s.py", line 95, in <module> test_ss(xmlfilepath, txtsavepath) File "/home/zh/local/flowChart/codes/ocr_s.py", line 68, in test_ss ftrainval = open(os.path.join(txtsavepath, '/trainval.txt'), 'w') PermissionError: [Errno 13] Permission denied: '/trainval.txt'

解决：

探索

print(txtsavepath) print(os.path.join(txtsavepath, 'trainval.txt')) print(os.path.join(txtsavepath, '/trainval.txt')) 这个三个分别输出： /home/zh/local/ocr/VOC2007/ImageSets/Main/ /home/zh/local/ocr/VOC2007/ImageSets/Main/trainval.txt /trainval.txt

解决办法：去掉斜杠
