使用powershell修改檔案修改日期

2022-09-05T17:24:00.000+08:00

之前在同步nextcloud時，發現有些檔案沒有修改日期

在command line下看時間都是1970/1/1，導致資料同步失敗

後來發現，只要檔案有更新，就會恢復同步的功能

所以研究了powershell，將所有檔案(包含子資料夾)的修改日期為1970/1/1的列出

然後將現在時間寫入lastwritetime欄位。

以下為powershell程式碼

# 取得檔案清單

$list = get-childitem -recurse -path "D:\NextCloud" | where-object {$_.LastWriteTime.Year -eq "1970"} | %{$_.FullName}

#變更修改日期

foreach($file in $list){(get-item $file).LastWriteTime =(get-date)}

chatterbot 從0.8.7升級到1.0.0遇到的狀況處理

2019-01-25T14:50:00.000+08:00

原來0.8.7的用法

'import_path' : 'chatterbot.logic.LowConfidenceAdapter',
'threshold' : 0, //0.0-1.0
'default_response' : '很抱歉，我聽不懂您的問題。'

1.0.0的時候拿掉了LowConfidenceAdapter，所以改成

'import_path' : 'chatterbot.logic.BestMatch',
'maximum_similarity_threshold' : 0, //0.0-1.0
'default_response' : '很抱歉，我聽不懂您的問題。'

**如果沒有設定maximum_similarity_threshold的話，預設值是0.95
