Environment Variable Configuration

After installing the CANN package, you must configure pyACL-related environment variables. Otherwise, import acl cannot be used.

If you have installed the cann-toolkit software package:

# Install Toolkit as the root user.
. /usr/local/Ascend/ascend-toolkit/set_env.sh 
# Install Toolkit as a non-root user.
. ${HOME}/Ascend/ascend-toolkit/set_env.sh

If you have installed the cann-nnrt software package:

# Install NNRT as the root user.
. /usr/local/Ascend/nnrt/set_env.sh
# Install NNRT as a non-root user.
. ${HOME}/Ascend/nnrt/set_env.sh

If you have installed the cann-nnae software package:

# Install NNAE as the root user.
. /usr/local/Ascend/nnae/set_env.sh 
# Install NNAE as a non-root user.
. ${HOME}/Ascend/nnae/set_env.sh

Configuring environment variables for an Atlas 500 AI edge station is described as follows:

. /opt/ascend/nnrt/set_env.sh

(Earlier version) Configuring environment variables for an Atlas 500 AI edge station is described as follows:

Add /home/data/miniD/driver/lib64 to the Python environment variable PYTHONPATH.
Example command:
```
export PYTHONPATH=/home/data/miniD/driver/lib64:$PYTHONPATH
```

Add /home/data/miniD/driver/lib64 to LD_LIBRARY_PATH.

Example command:

export LD_LIBRARY_PATH=/home/data/miniD/driver/lib64:$LD_LIBRARY_PATH
