I tried to create a "nonzero"  operator. I folloed the UDO guide. After create the udo config file, I used the tool snpe-udo-package-generator to create udo package. But I failed with the followed error:

2022-12-29 15:33:15,225 - 219 - WARNING - Force generation is set. Deleting existing udo Package at /home/.../work/SNPE/models/MyCustomUdoPackage
Traceback (most recent call last):
  File "/home/.../work/SNPE/snpe-1.68.0.3932/bin/x86_64-linux-clang/snpe-udo-package-generator", line 35, in <module>
    config_path=args.config_path)
  File "/home/.../work/SNPE/snpe-1.68.0.3932/lib/python/qti/aisw/converters/backend/custom_ops/snpe_udo_config.py", line 243, in setup_file_paths
    self.copy_udo_dir("utils", CUSTOM_OP_DIR, cpu_util_src_dir)
NameError: name 'CUSTOM_OP_DIR' is not defined
 
Then I check the code (snpe-1.68.0.3932/lib/python/qti/aisw/converters/backend/custom_ops/snpe_udo_config.py:243) .
 
           
    if "CPU" in udo_package.supported_runtimes:
                cpu_root = os.path.join(src_dir, 'CPU')
                cpu_src_dir = os.path.join(cpu_root, 'src')
                cpu_util_src_dir = os.path.join(cpu_src_dir, 'utils')
 
                self.copy_udo_dir("utils", CUSTOM_OP_DIR, cpu_util_src_dir)
                self.make_udo_dir(os.path.join(cpu_src_dir, 'ops'))

 
 
And I find the variable defination. It looks like I need to set the env "QNN_SDK_ROOT" , then the variable 'CUSTOM_OP_DIR' will be set.
(snpe-1.68.0.3932/lib/python/qti/aisw/converters/backend/custom_ops/snpe_udo_config.py:19)
QNN_SDK_ROOT = os.getenv("QNN_SDK_ROOT")
if QNN_SDK_ROOT is not None:
    SHARE_LOC_PREFIX = os.path.join(os.path.abspath(QNN_SDK_ROOT), 'target', 'x86_64-linux-clang', 'share', 'OpPackageGenerator')
    CUSTOM_OP_DIR = os.path.join(SHARE_LOC_PREFIX, 'CustomOp')
 
But  I don't know where to download 'QNN_SDK' and if this is necessary.
 
Any ideas?
Thanks

Dear developer,

The QNN SDK is no need to set to SNPE. Could you please share you conversion commands to us?

BR.

It seems like there is a bug starting from SNPE 1.62. Running with SNPE 1.61 fixed the problem for me

Did you find another solution for this apart from downgrade? I am using

snpe-udo-package-generator --config_path /data/octavf/trilu.json --output_path /data/octavf/triluUDOPack

And it crashes for same path missing from
/opt/qcom/aistack/snpe/2.12.0.230626/lib/python/qti/aisw/converters/backend/custom_ops/snpe_udo_config.py
