问题描述
运行时
pd.read_hdf('myfile.h5')
我收到以下回溯错误:
〜/.local/lib/python3.6/site-packages/pandas/io/pytables.py在 read_array(self，key，start，stop)2487 2488如果 isinstance(节点，表.VLArray): -> 2489 ret =节点[0] [开始:停止] 2490否则:2491 dtype = getattr(attrs，'value_type'，None)

tables/hdf5extension.pyx
tables/hdf5extension.pyx in tables.hdf5extension.VLArray._read_array()
ValueError:无法将此数组的WRITEABLE标志设置为True
ValueError: cannot set WRITEABLE flag to True of this array
不知道发生了什么.我试过基本上重新安装tables，pandas的所有内容，但不想阅读.
No clue what's going on. I've tried reinstalling tables, pandas everything basically, but doesn't want to read it.
推荐答案
您是否正在使用numpy 1.16?它与最新版本的pytables不兼容(请参见 https: //github.com/PyTables/PyTables/blob/v3.4.4/tables/hdf5extension.pyx#L2155 )，但pytables小组尚未发布固定版本: https://github.com/PyTables/PyTables/issues/719
Are you using numpy 1.16? It is incompatible with the latest release of pytables (see https://github.com/PyTables/PyTables/blob/v3.4.4/tables/hdf5extension.pyx#L2155) but the pytables team have not yet released a fixed version: https://github.com/PyTables/PyTables/issues/719
我发现解决此问题的唯一方法是降级numpy.
The only way I found to fix this is to downgrade numpy.
