Tensor Memory Allocation Error: 'holder_ should not be null.'

To resolve the 'Tensor holds no memory' error in PaddlePaddle, you need to call the Tensor::mutable_data() function before using the Tensor. This function allocates memory for the tensor and sets the 'holder_' to the allocated memory. This error typically occurs when you attempt to access or modify the data of a Tensor that hasn't been properly initialized with memory. By calling Tensor::mutable_data(), you ensure that the Tensor has a valid memory location and can be used for operations.
