brightway2.5中的Temporalis库AttributeError：'NoneType'对象没有属性'get'

Question

我从终端下载了temporalis库到brightway。在安装过程中，它发出警告，指出并非所有软件包都可以安装。错误如下：

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed.(https://i.stack.imgur.com/wtVhl.png)his behavior is the source of the following dependency conflicts.
brightway2 2.4.2 requires bw2calc==1.8.1, but you have bw2calc 2.0.dev16 which is incompatible.
brightway2 2.4.2 requires bw2data<3.99, but you have bw2data 4.0.dev33 which is incompatible.

这是来自 jupyter-lab 的错误代码的屏幕截图

但是由于 Temporalis 有效，我尝试使用以下链接中的代码来获取我的项目的结果

“https://github.com/brightway-lca/from-the-ground-up/blob/main/temporal/1%20-%20Introduction.ipynb”

在github上，但是我得到的第一个错误说brightway2.5与Temporalis兼容，所以我在anaconda上安装了新的brightway2.5的环境并再次尝试。然后jupyter-lab建议我在另一个错误中迁移项目，我也应用了它，但我仍然在第10行中收到这样的错误。你知道为什么以及如何解决这个问题吗？任何帮助将不胜感激。

Answer 1

您需要运行该函数:)

不是：

[3] projects.migrate_project_25

但是：

[3] projects.migrate_project_25()

如果这不起作用，您应该创建一个新项目并导入数据。

由于您使用的是 2.5，所以不要这样做：

[6] activity_name = 'copy_Köck building'

[7] my_activity = [x for x in ei if x['name'] == activity_name][0]

但是：

my_activity = bd.get_node(database="thesis  0.1", name='copy_Köck building')
