VTune randomly failing on loading .trace files

ejo — Wed, 07 Sep 2022 09:23:28 GMT

Hi,

I'm using Intel(R) oneAPI VTune(TM) Profiler 2021.6.0 (build 618723) Command Line Tool to profile a Python 3.8.11 application, but vtune -collect hotspots randomly fails with:

vtune: Error: Cannot load data file `/path/to/vtune_hs/data.0/13748-13758.0.trace' (Cannot resolve managed part of the application. Please archive your project data and provide it to the Technical Support for further investigation.).

Any idea how I can solve that issue?

The .trace file is attached.

Thank you!

Hi,

Thank you for posting in Intel Communities.

We are working on your issue internally and will get back to you with an update. can you try to upgrade your Vtune to the latest version and let us know if you are facing the same issue ?

Link: Download the Intel® VTune™ Profiler

>>If you continue to experience similar problems after upgrading Vtune, please share the details below.

1. OS details and processor details.

For windows:

1. Run command prompt as administrator

2. To set the environment variables run the below command:

<Vtune_installation_directory\2022.2.0\vtune-vars.bat>

example: C:\Program Files (x86)\Intel\oneAPI\vtune\2022.2.0\vtune-vars.bat

3. To run vtune-self-checker run the below command:

<Vtune_installation_directory\2022.2.0\bin64\vtune-self-checker.bat>

example: C:\Program Files (x86)\Intel\oneAPI\vtune\2022.3.0\bin64\vtune-self-checker.bat

For linux:

sh <oneapi_install_directory>/vtune/latest/bin64/vtune-self-checker.sh

(eg: sh /opt/intel/oneapi/vtune/latest/bin64/vtune-self-checker.sh)

Please attach the self-checker log (latest version of Vtune) to proceed further.

Thanks,

Dear Jaideep,
Thank you for the feedback.
Please find attached the log of the self-checker for the latest version of vtune.
The problem persists but it seems to be linked to Conda environments though. If I duplicate my Python environment using venv, vtune has no issue.

Hi,

Glad that you tried on another duplicate environment. The old conda environment might have some missing dependencies, hence, Vtune is throwing an error. You can continue working on duplicate environment as you mentioned that Vtune is working fine in it.

As your issue is resolved, can we discontinue monitoring this thread ?

Thanks,

Jaideep
