I have a same issue

Hi @Timaces , this problem may caused by different cython library, please try import nearest_neighbors rather than import nearest_neighbors.lib.python.nearest_neighbors as nearest_neighbors here.

I have the same issue, may be import utils.nearest_neighbors.lib.python.nearest_neighbors as nearest_neighbors works fine

I have tried what you said,but it doesn't work.Hava you solved this problem?

[ch19971118]

@ZhichaoWang970201 I have a same issue. Have you solve it?

hello ,have you solved this problem?

hello ,have you solved this problem?
I have solved this problem, and I thinks this problem dues to the error of "sh compile.sh". so you can try to run this statement and see whether exists error. if it has error, please solve them and "import nearest_neighbors.lib.python.nearest_neighbors as nearest_neighbors" will be ok. if it doesn't has error, then I don't know how to solve them. good luck~

Thank you for your reply:)

I have a familiar problem. Did you solve this problem?

I also ran into this problem, and I ended up finding out that it was caused by the unsuccessful compilation of the sh compile_op.sh.
Before compiling the compile_op.sh, go to utils/cpp_wrappers/compile_wrappers.sh and change !/bin/bash to #! /bin/bash
Then compile compile_op.sh, and upon success, import nearest_neighbors.lib.python. nearest_neighbors as nearest_neighbors no errors are reported

I has sloved this problem!when i run bash compile_op.sh,it still occur error，you should to check if It generate file that neareast_neighbors.cpython-37m-x86_64-linux-gnu.so in utils/nearest_neighbors/lib/python .The file is the same as your python version
