Hello,
I would like to use your library in an online scenario, but I can't find an example where the datasource don't have a fixed size.

How to add more data to an ArrayDataSource after having computed some nearest neighbors on the current data ?
Using the .run on ProgressiveKDTreeIndex only parses new points from the current fixed size ArrayDataSource.

I tried following the installation steps and encountered the below error while running 'make'. Any ideas?

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [benchmark/knn_table_benchmark] Error 1
make[1]: *** [benchmark/CMakeFiles/knn_table_benchmark.dir/all] Error 2
make: *** [all] Error 2

I am trying to build PANENE to use it within progressive-umap. I was able to follow the build instructions up until the step were we run make to build PANENE. This step fails with the following error message (from 57% into the process):

[...]

I am running Python 3.6.5 and 3.8.5, g++ 7.5.0, make 4.1 and cmake 3.10.2 and have run into this error on the following platforms:

• Ubuntu 16.04.7 on Linux 4.15.0-122-generic
• Ubuntu 18.04.4 LTS on Linux 4.15.0-122-generic
• Linux subsystem for Windows with Ubuntu 18.04.5 LTS on Linux 4.4.0-18362.

Any ideas on how to fix this?

Hi,

I have the following system Ubuntu 18.04 Architecture x86_64, with a local installation of Python 3.6.5 on my home account.

In order to proceed with the compilation, I edited the CmakeList.txt file to:
a) uncomment this section
#find_package(PythonInterp)
#if (NOT PYTHON_EXECUTABLE)

set(BUILD_PYTHON_BINDINGS OFF)

#endif()

b) add this line
set(BUILDPPYTHON_BINDINGS ON)

before these commands
if (BUILD_PYTHON_BINDINGS)
add_subdirectory(python)
endif()

c) add this line
set(PYTHON_EXECUTABLE /home/imarroquin/Python/Python-3.6.5/bin)

before these lines
message( STATUS "CMAKE_SYSTEM_PROCESSOR: " ${CMAKE_SYSTEM_PROCESSOR})
.....

The cmake command was successful. Then, I ran the command make which terminated with this error:

/bin/sh: 1: ./setup.py: Permission denied
python/CMakeFiles/target.dir/build.make:60: recipe for target 'python/build/timestamp' failed
make[2]: *** [python/build/timestamp] Error 126
CMakeFiles/Makefile2:367: recipe for target 'python/CMakeFiles/target.dir/all' failed
make[1]: *** [python/CMakeFiles/target.dir/all] Error 2
Makefile:140: recipe for target 'all' failed
make: *** [all] Error 2

Any suggestions?

I attached a text file with the output of both commands.

Many thanks,
Ivan
