无法在 Windows 10 上将模型链接到“en_core_web_md”

Question

我尝试在 Windows 10 上使用 Rasa 尝试 a chatbot made by a friend of mine。开始安装后端 through their tutorial 我很惊讶在使用 python -m spacy link en_core_web_md en 后无法将模型链接到“en_core_web_md”。以下是完整的错误信息：

Error: Couldn't link model to 'en_core_web_md'
Creating a symlink in spacy/data failed. Make sure you have the required
permissions and try re-running the command as admin, or use a
virtualenv. You can still import the model as a module and call its
load() method, or create the symlink manually.

C:\Users\antoi\Documents\Programming\Nathalie\Chatbot_RASA_room_reservation\cha_env36\lib\site-packages\en_core_web_md
-->
C:\Users\antoi\Documents\Programming\Nathalie\Chatbot_RASA_room_reservation\cha_env36\lib\site-packages\spacy\data\en_core_web_md


Creating a shortcut link for 'en' didn't work (maybe you don't have
admin permissions?), but you can still load the model via its full
package name: nlp = spacy.load('{name}')
Download successful but linking failed

这很奇怪，因为我能够在 Ubuntu 上这样做。 你有什么想法吗？

Answer 1

这是一个已知问题。实际上，您的错误消息正是给出了问题所在。该脚本无法为 en_core_web_md 创建符号链接（快捷方式）。执行以下操作以解决问题

• 转到您的目录：C:\Users\antoi\Documents\Programming\Nathalie\Chatbot_RASA_room_reservation\cha_env36\lib\site-packages\spacy\data\

• 创建到目的地的快捷方式：C:\Users\antoi\Documents\Programming\Nathalie\Chatbot_RASA_room_reservation\cha_env36\lib\site-packages\en_core_web_md

• 将其命名为en

---

如果您想知道如何创建快捷方式，以下屏幕截图可能会有所帮助

转到文件夹C:\Users\antoi\Documents\Programming\Nathalie\Chatbot_RASA_room_reservation\cha_env36\lib\site-packages\spacy\data\并右键单击并创建快捷方式

提供目标目录：在你的情况下它是 C:\Users\antoi\Documents\Programming\Nathalie\Chatbot_RASA_room_reservation\cha_env36\lib\site-packages\en_core_web_md 然后点击下一步

您必须将快捷方式命名为en。然后点击完成

Answer 2

按照您提供的日志。 可能是权限问题。

尝试以管理员权限打开 CMD，然后再次运行 spacy link 命令。

Answer 3

我所做的是以管理员身份打开 bash，然后运行命令：

python -m spacy link en_core_web_md en

如果您使用的是 virtualenv，请确保先激活上述 virtualenv。

Answer 4

您也可以在 cmd 中使用mklink 命令在所需文件夹中创建符号链接。

MKLINK [[/D] | [/H] | [/J]] Link Target

        /D      Creates a directory symbolic link.  Default is a file
                symbolic link.
        /H      Creates a hard link instead of a symbolic link.
        /J      Creates a Directory Junction.
        Link    Specifies the new symbolic link name.
        Target  Specifies the path (relative or absolute) that the new link
                refers to.
