ModuleNotFoundError：没有名为“camelot”的模块 | 适用于 Jupyter Notebooks 但不适用于 VSCode

Question

Goal: to get a working version of this tutorial with PDF , via. Visual Studio Code.

I am trying to install camelot , via. VSCode , using Poetry, but am having dependency problems.

This works in Jupyter Notebooks (bottom of post), but I am attempting to append to an existing.py project.

Code:

import glob
import camelot
import pandas as pd
import multiprocessing.dummy as mp

import ctypes
from ctypes.util import find_library
find_library("".join(("gsdll", str(ctypes.sizeof(ctypes.c_voidp) * 8), ".dll")))


PDF_LIST = glob.glob('../data/gri/reports/*.pdf')

def scrape_tables(pdf_filename):
    tables = camelot.read_pdf(pdf_filename)
    print("Total tables extracted:", tables.n)
    return tables

p = mp.Pool(len(PDF_LIST))
pdf_esg_scraped = p.map(scrape_tables, PDF_LIST)

pip install camelot :

Attempted Solution:

I got Ghostscript filepath output in Jupyter Notebook.

import ctypes
from ctypes.util import find_library
find_library("".join(("gsdll", str(ctypes.sizeof(ctypes.c_voidp) * 8), ".dll")))
>>> 'C:\\Users\\me\\Anaconda3\\Library\\bin\\gsdll64.dll'

Using this output, I need to "append new location to the PATH variable" .

However, this does not work still. Variations I have tried:

PATH=$PATH:C:\Users\me\Anaconda3\Library\bin\gsdll64.dll
PATH=$PATH:C:\\Users\\me\\Anaconda3\\Library\\bin\\gsdll64.dll
PATH=$PATH:'c/Users/me/Anaconda3/Library/bin/gsdll64.dll'
PATH=$PATH:'/mnt/c/Users/me/Anaconda3/Library/bin/gsdll64.dll'

Further, in order to get Poetry to work, I need to have PATH point to its location:

export PATH="$HOME/.poetry/bin:$PATH"

Can I have multiple PATH variables?

Sometimes modules were installed in VSCode but it couldn't recognize a new module, in the left button of VSCode click on the python version and change it to another version, and after it gets back to your first python version installed the module on it. change python version for work new installed module
