{"library":"Scipy","prompt":"Problem:\nI have two csr_matrix, c1 and c2.\n\nI want a new sparse matrix Feature = [c1, c2], that is, to stack c1 and c2 horizontally to get a new sparse matrix.\n\nTo make use of sparse matrix's memory efficiency, I don't want results as dense arrays.\n\nBut if I directly concatenate them this way, there's an error that says the matrix Feature is a list.\n\nAnd if I try this: Feature = csr_matrix(Feature) It gives the error:\n\nTraceback (most recent call last):\n  File \"yelpfilter.py\", line 91, in <module>\n    Feature = csr_matrix(Feature)\n  File \"c:\\python27\\lib\\site-packages\\scipy\\sparse\\compressed.py\", line 66, in __init__\n    self._set_self( self.__class__(coo_matrix(arg1, dtype=dtype)) )\n  File \"c:\\python27\\lib\\site-packages\\scipy\\sparse\\coo.py\", line 185, in __init__\n    self.row, self.col = M.nonzero()\nTypeError: __nonzero__ should return bool or int, returned numpy.bool_\n\nAny help would be appreciated!\n\nA:\n<code>\nfrom scipy import sparse\nc1 = sparse.csr_matrix([[0, 0, 1, 0], [2, 0, 0, 0], [0, 0, 0, 0]])\nc2 = sparse.csr_matrix([[0, 3, 4, 0], [0, 0, 0, 5], [6, 7, 0, 8]])\n</code>\nFeature = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
