IBM-db 與 Google Colab 的連接

Question

這是問題所在，我從系統收到以下錯誤消息，有人可以幫我解決嗎？ 這是我的輸入代碼

# Enter your Db2 credentials in the connection string below
# Recall you created Service Credentials in Part III of the first lab of the course in Week 1
# i.e. from the uri field in the Service Credentials copy everything after db2:// (but remove the double quote at the end)
# for example, if your credentials are as in the screenshot above, you would write:
# %sql ibm_db_sa://my-username:my-password@hostname:port/BLUDB?security=SSL
# Note the ibm_db_sa:// prefix instead of db2://
# This is because JupyterLab's ipython-sql extension uses sqlalchemy (a python SQL toolkit)
# which in turn uses IBM's sqlalchemy dialect: ibm_db_sa

%sql ibm_db_sa://xxxxxx77:xxxxxxxxxxxxxxxZR@ba99a9e6-d59e-4883-8fc0-d6a8c9f7a08f.c1ogj3sd0tgtu0lqde00.databases.appdomain.cloud:31321/bludb？security=SSL

用戶名和密碼是正確的，因為我使用 IBM-db API 連接方法，它很好並且成功連接到 IBM 雲數據庫

Connection info needed in SQLAlchemy format, example:
               postgresql://username:password@hostname/dbname
               or an existing connection: dict_keys([])
Can't load plugin: sqlalchemy.dialects:ibm_db_sa
Connection info needed in SQLAlchemy format, example:
               postgresql://username:password@hostname/dbname
               or an existing connection: dict_keys([])

Answer 1

這是我在 google colab 上嘗試的兩張圖片，安裝 ibm_db 和其他要求， 這是圖像顯示它沒有通過它

Answer 2

藍光數據庫；安全=SSL； 兩個半冒號起作用。 我和 co-lab 有同樣的問題
