[AWS] SSH 和 vsFTPD 衝到

說來話長，長話短說。ssh 突然爛掉了，連不進去我的 instance。

錯誤訊息如下

debug1: ssh_exchange_identification: 220 (vsFTPd 3.0.3)

debug1: ssh_exchange_identification: 530 Please login with USER and PASS.

debug1: ssh_exchange_identification: 421 Timeout.

原來 Amazon 有技術服務的，只要付錢就可以了 QQ

他給了一個非常好的建議，就是先 detach

一些 mount point 或是設定就參考這篇吧。

最後在經過把 vsftpd 移掉以後，重新attach，大師兄救回來了～

[keras] ValueError: Unknown initializer: GlorotUniform

Before:

from keras.models import load_model classifierLoad = load_model('model/modeltest.h5')

Works for me

import tensorflow as tf classifierLoad = tf.keras.models.load_model('model/modeltest.h5')
