Function Usage

Creates a tensor of the specified data type and tensor shape from a binary file.

Prototype

template <typename T>
std::unique_ptr<Tensor> CreateTensorFromFile(const char *data_file_path, const std::vector<int64_t> &dims, DataType dt, Format format = FORMAT_ND);

Parameters

Parameter	Input/Output	Description
T	Input	Tensor data type.
data_file_path	Input	Path of the binary file.
dims	Input	Tensor dimension vector.
dt	Input	Tensor data type.
format	Input	Tensor format. The default value is FORMAT_ND.

Returns

Parameter	Type	Description
-	std::unique_ptr<Tensor>	Smart pointer to the created tensor. If the operation fails, nullptr is returned.

Constraints

None

Examples

std::vector<int64_t> dims = {1};
auto tensor = CreateTensorFromFile<int64_t>(file_path.c_str(), dims, ge::DT_INT64, ge::FORMAT_ALL);
