It either means you are trying to save tensors which are reference of each other in which case it's recommended to save only the full tensors, and reslice at load time, or simply call `.contiguous()` on your tensor to pack it before saving.rrrUFrV) is_contiguous ValueErrorr/ is_cpu_placer7ctypesrintprodrTitem_SIZErNdata_ptrcastPOINTERc_ubyte ctypeslibas_arrayr`raNPDTYPESviewrbtobytes) rerfrknplengthbytes_per_item total_bytesptrnewptrrnpdtypes r_tobytesrs    !?vF& &  << $ $ &&++- .F6<<(N>)K // C ax [[fnnV^^< =F << + 8D }}6<<(yy!**5*9 <<>rc t|tstdt||j D]9\}}t|t j r!td|dt||j Dcic]E\}}|t|jjdd|jt||dGc}}Scc}}w)Nz5Expected a dict of [str, paddle.Tensor] but received zKey `z2` is invalid, expected paddle.Tensor but received .)rNrTr) isinstancedictrityper0rTensorstrrNsplitrTr)r r+r2s rrrs gt $CDM?
