Polyglot ImportError: cannot import name 'Locale' from 'icu'

Question

I was trying to run the polyglot for my sentimental analysis. After a lot of struggling,, I successfully installed Polyglot and pyicu. However when I ran my program, it gave me this error, and I don't know how to fix it

Answer 1

If you are on MacOSX with a version around 13 (M1 or other), you may need some extra steps beforehand to update the search paths:

1. Start by installing pkg-config and icu4c, necessary for pyicu to work:

   brew install pkg-config icu4c

2. Next, get the correct path to icu4c with the following command:

   brew info icu4c

3. You will get an output like this:

   ==> icu4c: stable 71.1 (bottled) [keg-only] C/C++ and Java libraries for Unicode and globalization https://icu.unicode.org/home /opt/homebrew/Cellar/icu4c/71.1 (262 files, 76.8MB) Poured from bottle on 2023-01-02 at 16:21:11 From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/icu4c.rb License: ICU ==> Caveats icu4c is keg-only, which means it was not symlinked into /opt/homebrew, because macOS provides libicucore.dylib (but nothing else).

   If you need to have icu4c first in your PATH, run:
   echo 'export PATH="/opt/homebrew/opt/icu4c/bin:$PATH"' >> ~/.zshrc
   echo 'export PATH="/opt/homebrew/opt/icu4c/sbin:$PATH"' >> ~/.zshrc

   For compilers to find icu4c you may need to set:
   export LDFLAGS="-L/opt/homebrew/opt/icu4c/lib"
   export CPPFLAGS="-I/opt/homebrew/opt/icu4c/include"

   For pkg-config to find icu4c you may need to set:
   export PKG_CONFIG_PATH="/opt/homebrew/opt/icu4c/lib/pkgconfig"

   ==> Analytics install: 375,450 (30 days), 1,501,837 (90 days), 5,475,904 (365 days) install-on-request: 6,461 (30 days), 20,819 (90 days), 87,520 (365 days) build-error: 15 (30 days)

Look at the export sections, in this case, my path to icu4c is: /opt/homebrew/opt/icu4c/

4. Use this path you got to update the following commands:

   export PATH="/opt/homebrew/opt/icu4c/bin:/opt/homebrew/opt/icu4c/sbin:$PATH"

   export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/opt/homebrew/opt/icu4c/lib/pkgconfig"

   export PYICU_INCLUDES=/opt/homebrew/opt/icu4c/include

   export PYICU_LFLAGS=-L/opt/homebrew/opt/icu4c/58.2/lib

5. You are now ready to follow the steps indicated by @Berkay 🤗

   • pip install pyicu

   • pip install morfessor

   • pip install pycld2

Answer 2

The problem is package dependency. Run the following commands in order:

1- pip3 install pyicu

2- pip3 install pycld2

3- pip3 install morfessor

That should work for your case. Also, for more detailed answers, check this link
