I use Windows and run the package on Anaconda. This is the error I received when running the second command of exercise 4 Traceback (most recent call last): File "examples/ctmrg_j1j2_c4v.py", line 192, in <module> main() File "examples/ctmrg_j1j2_c4v.py", line 51, in main state = read_ipeps_c4v(args.instate) File "\peps-torch\ipeps\ipeps_c4v.py", line 105, in read_ipeps_c4v global_args=global_args) File "\peps-torch\ipeps\ipeps.py", line 285, in read_ipeps state = IPEPS(sites, vertexToSite, lX=lX, lY=lY, peps_args=peps_args, global_args=global_args) File "\peps-torch\ipeps\ipeps.py", line 104, in __init__ assert site.dtype==self.dtype,"dtype of site "+str(coord)+" and IPEPS does not match" AssertionError: dtype of site (0, 0) and IPEPS does not match

Hi,

just add --GLOBALARGS_dtype complex128 In principle this should can be inferred from input file, but right now the dtype has to be explicitly passed in case of computation in complex domain.
