from nvm.pmemobj import PersistentObjectPool

data = np.load('/data/data/feature_100000_mat.npy') with PersistentObjectPool('hello_world.pmem', flag='c') as pool: if pool.root is None: pool.root = data

Traceback (most recent call last): File "", line 3, in File "/usr/lib64/python2.7/site-packages/nvm/pmemobj/pool.py", line 795, in root oid = self.mm.persist(value) File "/usr/lib64/python2.7/site-packages/nvm/pmemobj/pool.py", line 491, in persist raise TypeError("Don't know how to persist {!r}".format(cls_str)) TypeError: Don't know how to persist 'numpy:ndarray'
