# 函数：get_tensor_desc_size

| C函数原型 | size\_t aclGetTensorDescSize(const aclTensorDesc \*desc) |
| --- | --- |
| Python函数 | size = acl.get\_tensor\_desc\_size(desc) |
| 函数功能 | 获取Tensor描述占用的空间大小，同步接口。 |
| 输入说明 | desc：int，aclTensorDesc类型的指针地址。 需提前调用acl.create\_tensor\_desc接口创建aclTensorDesc类型。 |
| 返回值说明 | size：int，Tensor描述占用的空间大小。 |
| 约束说明 | 无 |
