keras可视化报错:OSError: `pydot` failed to call GraphViz.Please install GraphViz问题解决
在keras可视化模型输出时
from keras.utils import plot_model
plot_model(model, to_file=‘model.png’)
但是提示错误OSError: `pydot` failed to call GraphViz.Please install GraphViz
解决办法:
安装
1.pip install pydot
2.pip install graphviz
仍然报错!!!
修改代码:
1.修改set_prog函数:
def set_prog(self, prog): """Sets the default program. Sets the default program in charge of processing the dot file into a graph. """ path = r'D:\sw\anaconda3\envs\ccks\Library\bin\graphviz'# 例如我的:pip 安装路径 prog = os.path.join(path, prog) prog += '.exe' #self.prog = prog return prog
2.修改create函数
if prog is None: prog = self.prog assert prog is not None prog = self.set_prog('dot') #新增这行
