Question

这说明了如何配置Tensorflow https://jsfiddle.net/ov4nx7ad/

但是，当我尝试调整它以分析model.fit时，如下所示：

with tf.Session() as sess:
    sess.run(model.fit(x_train, y_train,
                        epochs=numberOfEpochs,
                        batch_size=128), options=run_options, run_metadata=run_metadata)

    # Profiling output
    trace = timeline.Timeline(step_stats=run_metadata.step_stats)
    with open('timeline.ctf.json', 'w') as f:
        f.write(trace.generate_chrome_trace_format())

我收到以下错误：

Traceback (most recent call last):
  File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\tensorflow\python\client\session.py", line 303, in __init__
    fetch, allow_tensor=True, allow_operation=True))

    (type(obj).__name__, types_str))
TypeError: Can not convert a History into a Tensor or Operation.

During handling of the above exception, another exception occurred:

知道我在做什么错吗？
