AttributeError: can't set attribute

Modify parts of the code:

v = tf.Variable(value, dtype=_convert_string_dtype(dtype), name=name)
    if isinstance(value, np.ndarray):
        v._keras_shape = value.shape
    elif hasattr(value, 'get_shape'):
        v._keras_shape = int_shape(value)
    v._uses_learning_phase = False
    # TODO: move to `tf.get_variable` when supported in public release.
    v.constraint = constraint  #Modify to v._constraint = constraint
    return v

Problem display:

when I was learning the file module, I encountered such a situation. How can I solve this situation?

2. Solutions

This involves a version problem. As we all know, Python is mainly divided into Python 2 and python 3. When we check the python official website, we can see that
(Python website address: www.python. ORG)

it can be seen that in versions above 3.0, the softspace attribute may have been removed, so use the command line py – 2 (if you do not install python2, you need to install python2 first, python2 and python3 can be installed at the same time, and use py – 2 and py – 3 to switch under Windows Environment) to switch to python2.7, Open a file to view the softspace property, and the command line executes normally.

urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host=‘localhost‘, port=8097): Max retries excee

After using visdom, the following problem occurs.

requests.exceptions.ConnectionError: HTTPConnectionPool(host=’localhost’, port=8097): Max retries exceeded with url: /env/main (Caused by NewConnectionError(‘<urllib3.connection.HTTPConnection object at 0x0000027F8769B7F0>: Failed to establish a new connection: [WinError 10061] Unable to connect due to aggressive rejection by the target computer.’))
[WinError 10061] Unable to connect because the target computer is actively rejecting.
Visdom python client failed to establish socket to get messages from the server. This feature is optional and can be disabled by initializing Visdom with `use_incoming_socket=False`, which will prevent waiting for this request to timeout.

visdom The above problem will also occur if it is not started.
Solution.

python -m visdom.server
