keras - TensorFlow 共享库错误；ImportError：libcuda.so.1：无法打开共享对象文件：没有这样的文件或目录

问题描述

我认为我的 cudatoolkit 版本有问题，即。10.0.130。我不明白这个错误信息。我想在 X 射线图像上使用 Gradcam（热图生成器）。这是来自 deeplearning.ai 的 AI for Medicine 的相同代码，我想在我的机器上运行它，我正在尝试为这个模型创建一个 REST API。

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

from keras.preprocessing.image import ImageDataGenerator
from keras.applications.densenet import DenseNet121
from keras.layers import Dense, GlobalAveragePooling2D
from keras.models import Model
from keras import backend as K
import keras.backend.tensorflow_backend as K
from keras.models import load_model
K.set_session
import util

文件 util.py 定义在同一目录中。

Using Theano backend.

解决方案

问题是我的虚拟环境中的 python 3.7。我降级到 python 3.6.5，一切似乎都很好。
