module 'pystac_client' has no attribute 'ItemCollection'

Hi

I run this example https://planetarycomputer.microsoft.com/docs/tutorials/cloudless-mosaic-sentinel2/
and i found following error:

AttributeError Traceback (most recent call last)
Cell In[23], line 1
----> 1 signed_items = pystac_client.ItemCollection([
2 planetary_computer.sign_assets(item) for item in items
3 ])
4 #print(signed_items)
5 data = (
6 stackstac.stack(
7 items,
(...)
13 .assign_coords(band=lambda x: x.common_name.rename("band")) # use common names
14 )

AttributeError: module 'pystac_client' has no attribute 'ItemCollection'

How to solve this problem?

從 issue 中連結的 cloudless mosaic Sentinel-2 教學，以及包含 pystac_client.ItemCollection 的 notebook 儲存格開始。檢查 notebook 的 imports 和已安裝套件的 API，以識別受支援的 ItemCollection 入口點，然後重新執行範例直到 stackstac 處理步驟，並確認 AttributeError 已消失。
