Quick Start

This section provides example commands for quickly installing the CANN software. For details, see the CANN Software Installation Guide.

You are advised to use the online installation (Conda) method. It allows you to directly install the software package of the latest or specified version without installing the dependencies in advance.

Preparing for Installation

  • Before installing the CANN, ensure that the NPU driver and firmware have been installed. Run the query command to query the driver information. If the driver information is returned and no exception occurs, you can continue to install the CANN. If the NPU driver and firmware are not installed, install them by referring to "Installing the NPU Driver and Firmware".

  • Except for the online installation (Conda) method, ensure that the Python environment and pip3 are available when using other installation methods. Currently, the CANN supports Python 3.7.x to 3.13.x.
  • Online installation (Conda): The installation directory of the Conda virtual environment and all its upper-level directories must have the 755 permission.
  • Offline installation: Click here to download the CANN package and upload it to any path in the installation environment.

To upgrade an earlier version to CANN 8.5.0, you must use parameters or uninstall all earlier versions and then install CANN 8.5.0. Otherwise, the installation may fail.

Sample Running

This sample uses the Abs operator as an example to demonstrate the operator call logic, process, and build script. Modify the API call script (*.cpp) and build script (CMakeLists) as needed. Note that the sample is compiled using CMake. Ensure that CMake 3.14 or later has been installed in the environment.

  1. Run the following command to configure environment variables:
    source ${install_path}/set_env.sh

    ${install_path} indicates the installation directory of the CANN software, for example, /usr/local/Ascend/cann.

  2. Create the sample code file test_abs.cpp in any directory (for example, /home) and write the following content to the file:
    #include <iostream>
#include <vector>
#include "acl/acl.h"
#include "aclnnop/aclnn_abs.h"

#define CHECK_RET(cond, return_expr) \

  3. Create the CMakeLists.txt file and write the following content to the file. Modify the content as needed.
    # Copyright (c) Huawei Technologies Co., Ltd. 2019. All rights reserved.

# CMake lowest version requirement

set(CMAKE_CXX_FLAGS_DEBUG "-fPIC -O0 -g -Wall")
set(CMAKE_CXX_FLAGS_RELEASE "-fPIC -O2 -Wall")

# Set the executable file name (for example, opapi_test) and specify the directory of the .cpp file of the operator to be run.
add_executable(opapi_test
               test_abs.cpp)

# Set ASCEND_PATH (CANN package directory) and INCLUDE_BASE_DIR (header file directory).
if(NOT "$ENV{ASCEND_HOME_PATH}" STREQUAL "")      
    set(ASCEND_PATH $ENV{ASCEND_HOME_PATH})
 else()
    set(ASCEND_PATH "/usr/local/Ascend/cann")
endif()
set(INCLUDE_BASE_DIR "${ASCEND_PATH}/include")
include_directories(
    ${INCLUDE_BASE_DIR}
    ${INCLUDE_BASE_DIR}/aclnn

# Set the path of the linked library file.
target_link_libraries(opapi_test PRIVATE
                      ${ASCEND_PATH}/lib64/libascendcl.so
                      ${ASCEND_PATH}/lib64/libnnopbase.so
                      ${ASCEND_PATH}/lib64/libopapi_math.so)

# The executable file is stored in the bin directory of the directory where the CMakeLists file is located.
install(TARGETS opapi_test DESTINATION ${CMAKE_RUNTIME_OUTPUT_DIRECTORY})
  4. In the directory where CMakeLists.txt is located, run the following command to create the build directory for storing the generated build file:
    mkdir -p build
  5. Go to the build directory, run the cmake command to build the file, and then run the make command to generate an executable file.
    cd build
cmake ../ -DCMAKE_CXX_COMPILER=g++ -DCMAKE_SKIP_RPATH=TRUE
make

    After the build is successful, the executable file opapi_test is generated in the bin folder in the build directory.

  6. Go to the bin directory and run the executable file opapi_test.
    cd bin
./opapi_test

    The following is an example of the execution result of the Abs operator:

    mean result[0] is: 1.000000
mean result[1] is: 1.000000
mean result[2] is: 1.000000
mean result[3] is: 2.000000
mean result[4] is: 2.000000
mean result[5] is: 2.000000
mean result[6] is: 3.000000
mean result[7] is: 3.000000
