I followd installation instructions and ran bash make.sh with no errors, however when I try to run the train.py script I get the following error: from ._dcn_v2 import lib as _lib, ffi as _ffi undefined symbol __cudaPopCallConfiguration any ideas as to why this is happening?

you need gcc-5 and g++5

Jun 29 '21 01:06 ssk1997

@ssk1997 I have both of these now getting the following:

Traceback (most recent call last): File "build.py", line 21, in raise ValueError('CUDA is not available') ValueError: CUDA is not available Traceback (most recent call last): File "build_double.py", line 21, in raise ValueError('CUDA is not available') ValueError: CUDA is not available

@ssk1997 ran sudo reboot because pytorch was not recognizing my gpu -- gpu is visible to pytorch tried to recompile the make file which ran without issues and when I try to train the model I am back to getting the ImportError undefined symbol: __cudaPopCallConfiguration

and I have both gcc5 and g++5 installed.

If it is helpful here is the output I am getting from running bash make.sh

Are you sure you have cuda 9.0, gcc-5 and g++-5 installed ? From the message you are using gcc-7. Try the command "gcc -v".

Yea I do now:
