【问题描述】:
我已经使用以下命令执行了张量流安装:
pip install --ignore-installed https://github.com/mind/wheels/releases/download/tf1.5-gpu-cuda91-nomkl/tensorflow-1.5.0-cp27-cp27mu-linux_x86_64.whl
这是适用于 CUDA 9.1 的最新 tensorflow 轮。 (比 CUDA 8.0 快 3 倍)
我可以在我的 python 代码中成功调用它。
如何让R中的keras调用上面python安装的tensorflow?之所以这么问是因为我默认的安装方式
keras::install_keras(method="conda", tensorflow = "gpu")
无法识别 cuda-9.1 库。
> conv_base <- keras::application_vgg16(
+ weights = "imagenet",
+ include_top = FALSE,
+ input_shape = c(150, 150, 3)
+ )
/home/ubuntu/anaconda2/envs/r-tensorflow/lib/python2.7/site-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
from ._conv import register_converters as _register_converters
Using TensorFlow backend.
Error: ImportError: Traceback (most recent call last):
File "/home/ubuntu/anaconda2/envs/r-tensorflow/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow.py", line 58, in <module>
from tensorflow.python.pywrap_tensorflow_internal import *
File "/home/ubuntu/anaconda2/envs/r-tensorflow/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow_internal.py", line 28, in <module>
_pywrap_tensorflow_internal = swig_import_helper()
File "/home/ubuntu/anaconda2/envs/r-tensorflow/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow_internal.py", line 24, in swig_import_helper
_mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory
这是因为 R 安装方法调用的 tensorflow 版本 1.5.0 仍然不适合 CUDA 9.1。

能否检查
R与reticulate::py_module_available("tensorflow")的python通信是否成功?如果它返回FALSE,那么您可能需要在 R 中配置 python 和 tensorflow 路径。另外,请查看reticulate::py_config()输出
