RuntimeError: (PreconditionNotMet) The third-party dynamic library (libnccl.so) that Paddle depends on is not configured correctly. (error code is libnccl.so: cannot open shared object file: No such file or directory)
Suggestions:
Check if the third-party dynamic library (e.g. CUDA, CUDNN) is installed correctly and its version is matched with paddlepaddle you installed.
Configure third-party dynamic library environment variables as follows:
Linux: set LD_LIBRARY_PATH by export LD_LIBRARY_PATH=...
Windows: set PATH by set PATH=XXX; (at /paddle/paddle/fluid/platform/dynload/dynamic_loader.cc:234) [Hint: If you need C++ stacktraces for debugging, please setFLAGS_call_stack_level=2`.
