config.txt

How should I fix these issues?

Hi @an-npt17, According to your config.txt log, TensorFlow-related algorithms are included in the build and are compiled successfully.

If you are using the Python extension, is it possible that you have multiple essentia Python packages on your system and a different one is being imported? You can double check the file path for the imported package to see if it corresponds to your manual installation from source: import essentia; print(essentia.__file__). The manual installation is located at /usr/local/lib/python3.10/dist-packages/essentia/ by default (replace with your Python version).

Also, if this is a default build (without static dependencies), you can check if the Python extension therein is linking to the TensorFlow library with ldd /usr/local/lib/python3.10/dist-packages/essentia/_essentia.cpython-310-x86_64-linux-gnu.so | grep tensorflow.

@dbogdanov thank you so much for your response.

In my issue, it seems like my essentia path is imported from /home/admin/.local/lib/python3.x/site-packages. However, when i switch the python path into dist-packages and import essentia, another issue appears:

Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python3.8/dist-packages/essentia/init.py", line 1, in from . import _essentia ImportError: /usr/local/lib/python3.8/dist-packages/essentia/_essentia.cpython-38-x86_64-linux-gnu.so: undefined symbol: _ZTIN8essentia9streaming10SourceBaseE

Where does this issue come from?

@an-npt17 Which options did you use to build with waf? (You can share the complete waf log is located in build/config.log).

You can check with ldd /usr/local/lib/python3.8/dist-packages/essentia/_essentia.cpython-38-x86_64-linux-gnu.so to see missing shared libraries. Waf build scripts install libessentia.so to /usr/local/lib/libessentia.so by default. Is it missing?

[an-npt17]

@dbogdanov here is my config.log file config.log

Apparently libessentia.so is missing, how could I configure it?
