Low-level h5py h5f error: expected bytes, found str
Low-level h5py h5f error: expected bytes, found str
我正在尝试创建一个具有修改缓存设置的 hdf5 文件处理程序,如下所示:
import h5py
import contextlib
def hdf5_handler(filename, mode="r"):
h5py.File(filename, "a").close()
propfaid = h5py.h5p.create(h5py.h5p.FILE_ACCESS)
settings = list(propfaid.get_cache())
settings[1] = 0
settings[2] = 0
propfaid.set_cache(*settings)
with contextlib.closing(h5py.h5f.open(filename, fapl=propfaid)) as fid:
return h5py.File(fid, mode)
#############
hdf5 = hdf5_handler("/tmp/foo.hdf5", "a")
但它给出了以下错误:
---------------------------------------------------------------------------

我还在下面找到了类似的代码,但它对我也不起作用,并出现同样的错误:
How to set cache settings while using h5py high level interface?
将您的字符串转换为字节之前:
hdf5 = hdf5_handler(bytes("/tmp/foo.hdf5",encoding="utf-8"), "a")
