# 可视化模型结构运行出错
from keras.utils import plot_modelif __name__ == "__main__": model = model.summary() plot_model(model, to_file='model.png', show_shapes=True)
首先：
pip install graphviz
pip install pydot
pip install pydot-ng
下载 graphviz-2.38.msi，存放到C:Program Files (x86)Graphviz2.38 ：https://graphviz.gitlab.io/_pages/Download/Download_windows.html
找到安装环境的pydot.py文件，例如D:anaenvstf1.15Libsite-packagespydot.py
pydot.py具体操作：
大概1793行，set_prog函数修改
def set_prog(self, prog): """Sets the default program. Sets the default program in charge of processing the dot file into a graph. """ #self.prog = prog #原方法就该句话 path = r'C:/Program Files (x86)/Graphviz2.38/bin' # 例如我的:F:Program FileAnacondaenvspython3.5Libsite-packagesbin prog = os.path.join(path, prog) prog += '.exe' return prog
大概1845行，create函数添加一句prog = self.set_prog('dot')：
if prog is None: prog = self.prog assert prog is not None prog = self.set_prog('dot') # 此处为添加的语句 if isinstance(prog, (list, tuple)): prog, args = prog[0], prog[1:] else: args = []
再次运行即成功解决问题。
