python之通过Python接口(interface)在Matlab中导入Tensorflow

我正在尝试使用一个 Python 脚本，该脚本使用 Keras/Tensorflow 作为更大的 Matlab 项目的一部分。 Matlab 可以很好地运行 Python 模块。直接从终端运行 Python 脚本工作正常。但是以一种有趣的方式将两者结合起来失败了:

Matlab:

% tensorflowTest.m 
mod = py.importlib.import_module('tensorf'); 
py.importlib.reload(mod); 

python :

# tensorf.py 
import tensorflow 

结果:

Error using pywrap_tensorflow><module> (line 52) 
Python Error: ImportError: Traceback (most recent call last): 
  File "/home/cfedk/shared/anaconda3/envs/keras/lib/python3.5/site-packages/tensorflow/python/pywrap_tensorflow.py", line 41, in <module>

这很有趣，因为 ImportError: libcudnn.so.6: cannot open shared object file: No such file or directory 是我们在安装 libcuddn 之前或如果 LD_LIBRARY_PATH 设置不正确。

如果直接导入 tensorflow 也会发生这种情况:py.importlib.import_module('tensorflow');

我宁愿为此求助于 RPC/单独的进程。我是否遗漏了一些明显的东西？

请您参考如下方法:

从终端启动 Matlab 或在启动器中设置 LD_LIBRARY_PATH 可解决此问题。
