Field Documentation

◆ byte_offset

uint64_t DLTensor::byte_offset

The offset in bytes to the beginning pointer to data.

Definition at line 146 of file dlpack.h.

◆ ctx

DLContext DLTensor::ctx

The device context of the tensor.

Definition at line 133 of file dlpack.h.

◆ data

void* DLTensor::data

The opaque data pointer points to the allocated data. This will be CUDA device pointer or cl_mem handle in OpenCL. This pointer is always aligns to 256 bytes as in CUDA.

For given DLTensor, the size of memory required to store the contents of data is calculated as follows:

static inline size_t GetDataSize(const DLTensor* t) {
  size_t size = 1;
  for (tvm_index_t i = 0; i < t->ndim; ++i) {
    size *= t->shape[i];
  }
  size *= (t->dtype.bits * t->dtype.lanes + 7) / 8;
  return size;
}

◆ dtype

DLDataType DLTensor::dtype

The data type of the pointer.

Definition at line 137 of file dlpack.h.

◆ ndim

int DLTensor::ndim

Number of dimensions.

Definition at line 135 of file dlpack.h.

◆ shape

int64_t* DLTensor::shape

The shape of the tensor.

Definition at line 139 of file dlpack.h.

◆ strides

int64_t* DLTensor::strides

strides of the tensor, can be NULL, indicating tensor is compact.
