我在我的jetson nano（jetpack 4.4，Cuda 10.2.89）中导入PyTorch时遇到了问题，我已经成功地从.whl文件中安装了它，它在我的pip3库中。但是当我导入它时，它显示了这个错误。请帮助。

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/parikshit/.local/lib/python3.6/site-packages/torch/__init__.py", line 188, in <module>
    _load_global_deps()
  File "/home/parikshit/.local/lib/python3.6/site-packages/torch/__init__.py", line 141, 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: libmpi_cxx.so.20: cannot open shared object file: No such file or directory```

cd /home/parikshit/.local/lib/python3.6/site-packages/torch ls
# You should find a .so file. Run the following command on that file ldd the_file_you_found.so
#In the output you should see "not found"
#To find out which apt packages provide this .so: sudo apt install apt-file sudo apt-file update
#Now search for that "not found" library file. Example: apt-file search blah.so.100
#In the first part of each line you will see the name of the file that you need to install. Example: sudo apt install lib-hello
#Enjoy!

前面的答案解决了我在Jetson Nano上找不到libmpi_cxx.so.20的问题，但我在导入Torch时遇到了另一个错误。
错误为：从焊炬._C导入 * ImportError：numpy.core.multiarray无法导入
如果您有问题导入 Torch ，因为未能导入numpy按照以下步骤。

pip install numpy -I

尝试执行以下操作：

cd /home/parikshit/.local/lib/python3.6/site-packages/torch
ls
# You should find a .so file. Run the following command on that file
ldd the_file_you_found.so
#In the output you should see "not found"
#To find out which apt packages provide this .so:
sudo apt install apt-file
sudo apt-file update
#Now search for that "not found" library file. Example:
apt-file search blah.so.100
#In the first part of each line you will see the name of the file that you need to install. Example:
sudo apt install lib-hello
#Enjoy!

第一个解决方案对我很有效！应该被认为是答案！我只需要在安装丢失的软件包之前做一个额外的步骤（在我的例子中是libopenmpi-dev）

$ sudo dpkg --remove --force-all libopenmpi-dev
$ sudo apt install libopenmpi-dev
