在PyScript中加载WordNet失败的问题求助

初始尝试触发资源未找到错误 #

最初使用以下代码引入NLTK和WordNet：

<py-env>
   - nltk
</py-env>
<py-script>
   import nltk
   from nltk.corpus import wordnet as wn
</py-script> 

触发LookupError(resource_not_found)，错误提示：

Please use the NLTK Downloader to obtain the resource: >>> import nltk >>> nltk.download('wordnet')

尝试自动下载资源失败 #

在代码中添加下载操作后：

<py-script>
   import nltk
   nltk.download('wordnet')
   from nltk.corpus import wordnet as wn
</py-script>

控制台返回错误：

writing to py-3f0adca1-a38a-4161-c36f-7e6548260aa5 [nltk_data] Error loading wordnet: <urlopen error unknown url type:
[nltk_data] https> true

手动下载解压WordNet包失败 #

参考相关解决方案后，使用以下代码手动获取并解压WordNet压缩包：

from js import fetch
from pathlib import Path
import asyncio, os, sys, io, zipfile

response = await fetch('https://github.com/nltk/wordnet/archive/refs/heads/master.zip')
js_buffer = await response.arrayBuffer()
py_buffer = js_buffer.to_py()  # this is a memoryview
stream = py_buffer.tobytes()  # now we have a bytes object

d = Path("/nltk/wordnet")
d.mkdir(parents=True, exist_ok=True)

Path('/nltk/wordnet/master.zip').write_bytes(stream)

zipfile.ZipFile('/nltk/wordnet/master.zip').extractall(
    path='/nltk/wordnet/'
)

出现解压错误：

self._RealGetContents()

File "/lib/python3.10/zipfile.py", line 1325, in _RealGetContents
raise BadZipFile("File is not a zip file")
zipfile.BadZipFile: File is not a zip file

尝试替代库wn失败 #

尝试安装wn库替代：

await micropip.install('https://files.pythonhosted.org/packages/ce/f1/53b07100f5c3d41fd33fc78ebb9e99d736b0460ced8acff94840311ffc60/wn-0.9.1-py3-none-any.whl')

触发依赖缺失错误：

JsException(PythonError: Traceback (most recent call last): File "/lib/python3.10/asyncio/futures.py", line 201, in result raise self._exception File "/lib/python3.10/asyncio/tasks.py", line 232, in __step result = coro.send(None) File "/lib/python3.10/site-packages/_pyodide/_base.py", line 500, in eval_code_async await CodeRunner( File "/lib/python3.10/site-packages/_pyodide/_base.py", line 353, in run_async await coroutine File "", line 14, in File "/lib/python3.10/site-packages/wn/init.py", line 47, in from wn._add import add, remove File "/lib/python3.10/site-packages/wn/_add.py", line 21, in from wn.project import iterpackages File "/lib/python3.10/site-packages/wn/project.py", line 12, in import lzma File "/lib/python3.10/lzma.py", line 27, in from _lzma import * ModuleNotFoundError: No module named '_lzma' )

请问上述操作中哪里出错了？
