When I installed torch according to the instructions, I encountered some problems. The following is the relevant version information of Xavier I currently use：
nvidia@Xavier:~$ cat /etc/nv_tegra_release # R32 (release), REVISION: 5.1, GCID: 27362550, BOARD: t186ref, EABI: aarch64, DATE: Wed May 19 18:16:00 UTC 2021
nvidia@Xavier:~$ nvcc --version nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2019 NVIDIA Corporation Built on Wed_Oct_23_21:14:42_PDT_2019 Cuda compilation tools, release 10.2, V10.2.89
The version of torch I installed is pytorch v1.7.0.
When I check the torch installation, python reports the following error:
>>> import torch Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/nvidia/.local/lib/python3.6/site-packages/torch/__init__.py", line 189, in <module> _load_global_deps() File "/home/nvidia/.local/lib/python3.6/site-packages/torch/__init__.py", line 142, in _load_global_deps ctypes.CDLL(lib_path, mode=ctypes.RTLD_GLOBAL) File "/usr/lib/python3.6/ctypes/__init__.py", line 348, in __init__ self._handle = _dlopen(self._name, mode) OSError: libcurand.so.10: cannot open shared object file: No such file or directory
Libcurand.so.10 does not seem to be installed in my Xavier. I found that the previous discussion on the forum did not involve jetpack4.5.1, so I would like to know whether I also encountered the problem of version adaptation. Looking forward to an answer.
