Hey Sanghoon (@a11525),
I tried to reproduce your problem, but I can't when running the code that you have provided. Everything runs without problems. Something must be wrong with your setup. The path in your error message (/home/sanghoon/anaconda3/envs/rdkit_env/bin/python3.9
) indicates that you are trying to run this in a Python 3.9 environment. According to the setup instructions in the README, the current version of ChemDataExtractor is only compatible with Python 3.5-3.8. This might be the root of the problem. I have had problems with the proper installation of ChemDataExtractor since version 2.1. I recommend running it with this Docker image.
Kind regards, Otto
One thing just came to my mind:
Have you run cde data download
in the command shell in your environment?
Hello Otto @OBrink
My problem seems to be an error due to a version conflict during installation. When I installed a new environment and used pip install chemdataextractor2 , it installed well. However, when importing Chemdataextractor.doc.Paragraph, the int issue of issue #29 was resolved, and the np.float issue that occurred was also corrected. After that, the nltk package gives me AttributeError: partially initialized module 'nltk' has no attribute 'data' (most likely due to a circular import) has occurred. Here is the part where the error occurred. how should i solve it? sent_tokenizer=nltk.data.LazyLoader("tokenizers/punkt/english.pickle"),
Kind regards, Sanghoon Lee
The problem was solved by changing all np.float to float and executing import nltk.data first before chedataextractor import. thanks. However, when I call cems or token using Document or Paragraph in a specific sentence, Ran out of input problem occurs. What is the problem? The sentence I wanted did not work, so I followed the example of the document, but it did not work.
para_exam = Paragraph('1,4-Dibromoanthracene was prepared from 1,4-diaminoanthraquinone. 1H NMR spectra were recorded on a 300 MHz BRUKER DPX300 spectrometer.') para_exam.tokens

Hello Sanghoon,
If I understand this right, the error occurs when trying to load a model that ChemDataExtractor needs for tokenization. This seems odd. Have you tried running cde data download
in your command shell as suggested by the error message?
I have to say, that I don't know how to fix this in your environment. I have given up on trying to set up an environment with the current version of ChemDataExtractor on my computer and I am running it using Docker now. Working with a Docker image that comes with the preinstalled package with all dependencies has the advantage that it's an encapsulated environment that is pre-configured and just works out of the box.
I have written some instructions on how to work with the ChemDataExtractor Docker image. After installing Docker it should work as described there. I hope this helps.
Kind regards, Otto
Hello,
I'm trying to use ChemDataExtractor2 for my project. I followed the instructions in the documentation, installed the package via pip (pip install chemdataextractor2), and tried to run the example code provided. However, I'm encountering a ModelNotFoundError stating "Could not load models/punkt_chem-1.0.pickle. Have you run cde data download?". ( my code from chemdataextractor.doc import Paragraph strings = "Ring A is -C3-C12 cycloalkyl, 3- to 14-membered heterocyclyl having 1 to 4 heteroatoms selected from oxygen, nitrogen, and sulfur, -Ce-Cio aryl, or 5- to 14-membered heteroaryl having 1 to 4 heteroatoms selected from oxygen, nitrogen, and sulfur, wherein each cycloalkyl, heterocyclyl, aryl, or heteroaryl of Ring A is optionally substituted with one or more substituents selected from the group consisting of halogen, -C1-C6 alkyl, -OR, -OC(O)R’, -NR2, -NRC(O)R’, -NRS(O)2R’, -CN, -NO2, -SR, -C(O)R’, -C(O)OR, -C(O)NR2, -S(O)2R’, and -S(O)2NR2;" para = Paragraph(strings) para.sentences )
I've attempted to uninstall and reinstall the package several times, but the error persists. Additionally, during the installation of ChemDataExtractor2, I noticed an error occurring midway but the installation seemed to continue regardless. Here's the error message:
ERROR: Command errored out with exit status 1: /home/sanghoon/anaconda3/envs/rdkit_env/bin/python3.9 -u -c 'import io, os, sys, setuptools, tokenize; sys.argv[0] = ... (truncated for readability)
Then followed by a warning:
WARNING: Discarding https://files.pythonhosted.org/packages/ce/5e/8f21b3f32ea3566764d1c90f4360703be7d1739ed7b51cbf89bed00fa331/spacy-2.1.0.tar.gz#sha256=e3dbde5b560fb9dd3706bd6838e66e28119b6aa17bcb0711d53e95c830bcf0a7 (from https://pypi.org/simple/spacy/) (requires-python:>=2.7,!=3.0.,!=3.1.,!=3.2.,!=3.3.).

I am unsure how to resolve this issue. Could you provide some guidance or assistance on this matter? Any help would be greatly appreciated.
Thank you.
