error: use of deleted function

[powderfool000]

system setup:

Ubuntu LTS 16.04
NVidia drivers, 418.67
CUDA Toolkit, v9.2
NVidia GeForce 940MX (Compute Capability 5.0)

when run 'make python_cpu', i got the following error below

/usr/include/boost/python/object/value_holder.hpp:137:13: error: use of deleted function ‘cufhe::Ctxt::Ctxt(const cufhe::Ctxt&)’
BOOST_PP_REPEAT_1ST(N, BOOST_PYTHON_UNFORWARD_LOCAL, nil)
^
In file included from python/lib/fhepy.cpp:23:0:
./include/cufhe.h:109:3: note: declared here
Ctxt(const Ctxt& that) = delete;
^
Makefile:97: recipe for target 'python/lib/fhepy_cpu.o' failed
make: *** [python/lib/fhepy_cpu.o] Error 1

Any idea how i should go about this? Or is there anything i can check?

I am getting something similar: see dump below.

any thoughts? this is on a freshly created AWS instance of type Deep Learning AMI (Ubuntu 18.04) Version 27.0 (ami-0a7789c77135a5f8a). thanks.

I also get this, both for python_cpu and python_gpu.
