pickling error while doing joblib, or numba #1448

Open rsinghoyla opened 4 years ago

rsinghoyla commented 4 years ago

I get a TypeError: can't pickle open3d.open3d.geometry.PointCloud objects when I try to parallelize a for loop to (multiple) query the KDTree. I have tried joblib and numba and both give me same error.

my code is basically

         [k, idx, _] = pcd_tree.search_knn_vector_3d(pcd.points[i], 1000)
          return idx
results = Parallel(n_jobs=num_cores, verbose=50)(delayed(
    myfunc)(i)for i in my_list)

Is there an alternate fast method for multiple querying the KD Tree?

Thanks!

Yes. pickling is actually a long hanging issue. To querying KDTree using multi-threading, we are preparing better API for that. Please stay tuned.
