Python PyTables写入错误

我正在以以下方式创建和填充PyTables Carray：

#a,b = scipy.sparse.csr_matrix
f = tb.open_file('../data/pickle/dot2.h5', 'w')
filters = tb.Filters(complevel=1, complib='blosc')
out = f.create_carray(f.root, 'out', tb.Atom.from_dtype(a.dtype),
        shape=(l, n), filters=filters)

bl = 2048
l = a.shape[0]
for i in range(0, l, bl):
    out[:,i:min(i+bl, l)] = (a.dot(b[:,i:min(i+bl, l)])).toarray()

脚本运行了近两天，我估计至少还需要4天

但是，我突然收到了这个错误堆栈跟踪：

我真的不知道问题是什么，因为它在大约四分之一的数据集上运行良好。磁盘空间可用。

IIRC这种错误可能是由文件损坏引起的。您是否可以通过使用HDF5查看器打开HDF5文件来检查其完整性，例如，或使用？如果没有此错误，它现在已损坏…您没有尝试在多个线程中写入同一文件，是吗？不，我没有，我知道这不适用于PyTables临时。该文件是本地存储还是远程存储？
