我正在尝试使用 TensorFlow 中的 plot_model 函数来绘制我的模型并将其保存到 Ubuntu 22.04 上的文件中。Pycharm 2024.1.3。python 3.12。Tensorflow 2.16.1。我假设 Pydotplus 和 Graphviz 已正确安装，或者我遗漏了某些内容。文件已创建，但已损坏（0 字节）并且无法打开。

outputs=outputs)
model.name = model_parameters["model_name"]
return model
我尝试过 pydot、pydotplus 和 pydot-ng（从 pip 安装）——结果是一样的。Graphviz 可以通过 \'sudo apt install graphviz\' 或 \'pip install graphviz\' 安装。文件的扩展名无关紧要——我尝试过 jpg、png、pdf。安装 graphviz 后，PC 已重新启动。
Traceback 错误的最后一行没有给我任何信息，我陷入了困境。我发现 dot 出了问题，它生成了状态 [-6]，但我不知道是什么问题。我猜是生成图像或/和将其写入文件时出了问题（因为崩溃后文件为空）。另一个想法是一个或多个层或模型本身无法转换为 dot。
有人能帮助我解决这个问题吗？或者建议我至少应该从哪里开始深入研究？我将不胜感激任何人提供的帮助。

从旧信令服务器迁移到新信令服务器后，我尝试使用 Talk 时遇到了问题，在 Chrome 浏览器上收到“无法建立信令连接。正在重试...”错误，但 Firefox 或 Edge 等其他浏览器可以正常工作。
从 nc 服务器 ping 和 telnet 信号成功。
我尝试删除浏览器缓存和 Cookies，并重置 Chrome 扩展程序。
我还尝试禁用 NC 和信令服务器上的 UFW 防火墙
