运行S3DIS数据时，epoch为0
亲爱的胡老师： 您好，我是一名本科生，最近在看您的文章，在运行的时候“sh jobs_6_fold_cv_s3dis.sh”这一条命令时，遇到了 “EPOCH 0* Caught a NaN error : 3 2 root error(s) found. (0) Invalid argument: ValueError: attempt to get argmin of an empty sequence Traceback (most recent call last):
File "/home/wlw/.local/lib/python3.6/site-packages/tensorflow/python/ops/script_ops.py", line 209, in call ret = func(*args)
File "/home/wlw/.local/lib/python3.6/site-packages/tensorflow/python/data/ops/dataset_ops.py", line 514, in generator_py_func values = next(generator_state.get_iterator(iterator_id))
File "main_S3DIS.py", line 114, in spatially_regular_gen cloud_idx = int(np.argmin(self.min_possibility[split]))

ValueError: attempt to get argmin of an empty sequence”这个错误，学生刚刚进入学习阶段，或许范一些很简单的错误，但还是希望您能不吝赐教，解答一下，十分感谢您的帮助。
你好 请问问题解决了吗？
是的，这是数据路径的问题，你要检查所有文件的数据路径，要把“/data/.......”的“/”去掉就可以解决了
已解决，非常感谢！

同学你好，我目前也在跑这个网络，想请教你一些问题，方便的话请加一下我的微信：Yaomengmeng_1996

谢谢你，我的异常是计算出了NaN，也是路径的问题，/data...忘记改了 hahha
