r - 错误 : Python module 'cleannlp' not found. 安装:pip install cleannlp in R

Question

我在 ubuntu 18.4 上使用 R studio，特别是 cleannlp 包来根据 this tutorial found here https://statsmaths.github.io/cleanNLP/state-of-union.html 分析文本.

根据找到的安装说明 here - https://statsmaths.github.io/cleanNLP/ ，到目前为止，我已经像这样安装了 cleannlp install.packages("cleanNLP")在 Rstudio 的控制台中。此外，我已经安装了它的模块 pip install cleannlp在终端。据我所知，这两种安装都没有遇到任何问题。

如安装说明所示，cleannlp 有 4 个后端:

cnlp_init_stringi(locale="en_GB")
cnlp_init_udpipe(model_name="english")
cnlp_init_spacy(model_name="en")
cnlp_init_corenlp(lang="en")

使用 stringi 或 udpipe 似乎没有任何问题。但是，使用 spacy 和 corenlp 后端似乎会引发此错误

Error: Python module 'cleannlp' not found. Install with: pip install cleannlp
4. stop(msg, call. = (msg == ""))
3. assert(!is.null(disc$required_module_path), "Python module 'cleannlp' not found. Install with:\n pip install cleannlp")
2. check_python()
1. cnlp_init_spacy("/usr/local/lib/python3.6/")

我相当肯定 python 包安装成功，从以下推断:

我尝试过的一些事情包括

没有路径cnlp_init_spacy()

这给了我:

Error: Python module 'cleannlp' not found. Install with: pip install cleannlp
4. stop(msg, call. = (msg == ""))
3.
assert(!is.null(disc$required_module_path), "Python module 'cleannlp' not found. Install with:\n pip install cleannlp")
2. check_python()
1. cnlp_init_spacy()

我是否与任何一个后端(spacy 和 corenlp)都给我带来麻烦没有区别。

sudo pip install sudo -H pip install sudo -H pip3 install 和 sudo pip3 install 所有这些似乎都工作正常。但是，我想知道 R 选择哪个安装是否有问题。所以我卸载并再次尝试。此外，我似乎对 R 之外的 python 有任何问题。

Answer 1

可能是 R 使用的 python 环境没有安装“cleannlp”。您可以通过以下方式检查:

install.packages("reticulate")
library(reticulate)
py_discover_config(required_module="cleannlp")

这应该指向您的 anaconda3 路径。如果它指向另一个环境，例如r-miniconda，您可以使用以下命令进行更改:

Sys.setenv(RETICULATE_PYTHON = path)

其中 path 是您到 anaconda 的路径，在 Mac 中通常具有以下形式:“/Users/YOUR_NAME/anaconda3/bin/python”
现在运行:

py_discover_config(required_module="cleannlp")

再次检查它是否在您的 anaconda3 python 环境中找到“cleannlp”。
如果可行，那么您现在可以运行:

cnlp_download_corenlp()
cnlp_init_corenlp(lang="en")
