我有一棵树，它的一个分支存储着一根绳子。当我阅读 usinguproot.open()然后使用该方法时arrays()，我得到以下信息：
>>> array_train['backtracked_end_process']
<ObjectArray [b'FastScintillation' b'FastScintillation' b'FastScintillation' ... b'FastScintillation' b'FastScintillation' b'FastScintillation'] at 0x7f48936e6c90>
我想使用这个分支来创建掩码，通过这样做
array_train['backtracked_end_process'] != b'FastScintillation'
但不幸的是这会产生一个错误：
---------------------------------------------------------------------------
ValueError Traceback (most recent call last)

有人对如何进行有任何建议吗？能够将其转换为 anumpy.chararray已经可以解决问题，但我不知道该怎么做。
