2023-06-08 10:47:49.014852: W tensorflow/stream_executor/platform/default/dso_loader.cc:59] Could not load dynamic library 'cudart64_101.dll'; dlerror: cudart64_101.dll not found 2023-06-08 10:47:49.014998: I tensorflow/stream_executor/cuda/cudart_stub.cc:29] Ignore above cudart dlerror if you do not have a GPU set up on your machine.

这是一段TensorFlow的警告信息，指出找不到cudart64_101.dll这个动态链接库文件。这个文件是CUDA（Compute Unified Device Architecture）运行时库的一部分，用于支持在GPU上运行的TensorFlow程序。如果你的电脑没有GPU或者没有安装CUDA，那么这个警告信息可以忽略。如果你需要在GPU上运行TensorFlow程序，需要安装相应的CUDA和cuDNN等库文件，并配置好环境变量。

看起来这是一个 TensorFlow 在 Windows 操作系统上运行时遇到的警告和错误消息。警告消息 "Internal: Invoking ptxas not supported on Windows" 表示在 Windows 操作系统上使用 ptxas 编译器的操作不受支持，因此必须依赖驱动程序来执行 ptx 编译。错误消息的具体内容需要查看 Traceback 中的栈跟踪信息才能确定。请提供更多上下文信息以获得更准确的答案。

这个错误是由于TensorFlow 2.x版本中`tf.Summary`已被弃用所致。相反，你应该使用`tf.summary.Summary`。你需要将代码更新为：

summary = tf.summary.Summary(value=[tf.summary.Summary.Value(tag='reward', simple_value=reward)])

这样就可以避免这个错误了。另外，还需要注意，TensorFlow 2.x版本中`tf.summary.FileWriter`已经被弃用，应该使用`tf.summary.create_file_writer`来创建一个`tf.summary.FileWriter`的实例。
