@amwfarid Could you please try the solution from here?

Hello, sorry for the late reply!
This is because vdbfusion was not compiled with pyopenvdb
support enabled. The way I check this on the build system is qutie dirty, and couldn't find a better solution:
https://github.com/PRBonn/vdbfusion/blob/8d01832419050aed1105e666040c4e5d3a14c96c/src/vdbfusion/pybind/CMakeLists.txt#L5
You can debug this problem yourself by firing up a python shell and try to import the library import pyopenvdb
. Is this fails, then the rest fails. Probably something went wrong while building OpenVDB from source.

@nachovizzo Thank you very much for the response and help!
I managed to get rid of the attribute error (but then got another error with FloatGrid
). The issue you linked to gave some good hints. Here's what I did:
I made sure I uninstalled the vdbfusion on my venv
pip uninstall vdbfusion
I reinstalled OpenVDB in the way prescribed here (conda approach):
git clone --depth 1 https://github.com/nachovizzo/openvdb.git -b nacho/vdbfusion \
&& cd openvdb \
&& mkdir build && cd build \
&& cmake \
-DOPENVDB_BUILD_PYTHON_MODULE=ON \
-DUSE_NUMPY=ON \
-DPYOPENVDB_INSTALL_DIRECTORY="/home/farid/projects/make_it_dense/venv/lib/python3.8/dist-packages" \
-DCMAKE_POSITION_INDEPENDENT_CODE=ON \
-DUSE_ZLIB=OFF \
..\
&& make -j$(nproc) all install \
&& cd ../.. \
&& rm -rf openvdb
However importantly, I set DPYOPENVDB_INSTALL_DIRECTORY
to point to my venv python install directory instead.
Afterwards, I went to the root of vdbfusion and did make install
The attribute error went away, but now I get this:

ValueError: GridType: <class 'pyopenvdb.FloatGrid'> not supported
I recognize that we are using your fork of OpenVDB because of a wrong value issue related to FloatGrid, but this one says outright that the class is not supported. might there be a version mismatch somewhere?
from make_it_dense.
Almost there, could you paste the output of this command: python3 -c "import pyopenvdb; print(dir(pyopenvdb))" | tr ',' '\n' | grep Grid
. In my case the output is:
'BoolGrid'
'FloatGrid'
'GridClass'
'GridTypes'
'Vec3SGrid'
'readAllGridMetadata'
'readGridMetadata'
The reason behind all this madness is to provide a way to pass a Python object back and forth without having to re-convert or to even think about the C++ native type. The code for this is:
template <>
struct type_caster<openvdb::FloatGrid::Ptr> {
public:
/// Converts Python to C++
bool load(handle src, bool /*unused*/) {
PyObject* source = src.ptr();
boost::python::extract<typename openvdb::FloatGrid::Ptr> grid_ptr(source);
if (!grid_ptr.check()) return false;
value = grid_ptr();
return (value && (PyErr_Occurred() == nullptr));
}
/// Converts from C++ to Python
static handle cast(openvdb::FloatGrid::Ptr src, return_value_policy, handle) {
if (!src) return none().inc_ref();
py::module::import("pyopenvdb").attr("FloatGrid");
boost::python::object obj = boost::python::object(src);
auto out = reinterpret_borrow<py::object>(obj.ptr());
return out.release();
}
PYBIND11_TYPE_CASTER(openvdb::FloatGrid::Ptr, _("pyopenvdb.FloatGrid"));
};

@nachovizzo I'm terribly sorry for responding late! I couldn't access the server to test the fix.
It finally worked! Indeed, the "-I" managed to fix the issue and now I can run the code. Thank you very much!
