I think this issue may be caused by an incorrect contraction of dimensions.\n\n### Code to Reproduce the Bug\n\n```shell\nfrom qutip import *\r\nA = qeye([[1], [1, 3]])\r\ntensor_contract(A, (2, 5))\n```\n\n\n### Code Output\n\n```shell\nTraceback (most recent call last):\r\n  File \"from qutip import *.py\", line 4, in <module>\r\n    tensor_contract(A, (2, 5))\r\n  File \"/opt/anaconda3/envs/qutip/lib/python3.12/site-packages/qutip/core/tensor.py\", line 341, in tensor_contract\r\n    qmtx = qtens.reshape((l_mtx_dims, r_mtx_dims))\r\n           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\r\nValueError: cannot reshape array of size 9 into shape (1,1)\n```\n\n\n### Expected Behaviour\n\nIt should output a matrix with a shape (1, 1) instead of size 9. \n\n### Your Environment\n\n```shell\nQuTiP Version:      5.0.4\r\nNumpy Version:      2.1.3\r\nScipy Version:      1.14.1\r\nCython Version:     None\r\nMatplotlib Version: 3.9.2\r\nPython Version:     3.12.7\r\nNumber of CPUs:     8\r\nBLAS Info:          Generic\r\nINTEL MKL Ext:      False\r\nPlatform Info:      Darwin (arm64)\n```\n\n\n### Additional Context\n\n_No response_",
