我尝试在jupyter notebook中创建session并使用jupyter notebook API执行代码，代码如下：

url = base + '/api/sessions'
    params = '{"path":\"%s\","type":"notebook","name":"","kernel":{"id":null,"name":"env37"}}' % file_name
    response = requests.post(url, headers=headers, data=params)
    session = json.loads(response.text)
    kernel = session["kernel"]

    # 讀取notebook檔案，並獲取每個Cell裡的Code
    url = base + '/api/contents' + notebook_path
    response = requests.get(url, headers=headers)
    file = json.loads(response.text)
    code = [c['source'] for c in file['content']['cells'] if len(c['source']) > 0]
    ws = create_connection("ws://127.0.0.1:8888/api/kernels/" + kernel["id"] + "/channels?session_id" + session["id"],
                           header=headers)
    for c in code:
        ws.send(json.dumps(send_execute_request(c)))

    # 我們只拿Code執行完的訊息結果，其他訊息將被忽略
    for i in range(0, len(code)):
        try:
            msg_type = ''
            while True:
                rsp = json.loads(ws.recv())
                msg_type = rsp["msg_type"]

字符串
但是在“ws.recv（）"中，有一个错误：raise WebSocketConnectionClosedException（“socket is already closed.”）。
jupyter notebook cmd显示：

当我在jupyter notebook UI中关闭内核env37时，它显示：

我猜这是WebSocket在回复发送之前被关闭了，但是为什么以及如何解决呢？这个问题也发布在jupyter community forum中
