ERROR: Cannot install en-core-web-trf because these package versions have conflicting dependencies

I use the following commands (from spacy website here) to install spacy and en_core_web_trf under Windows 10 home 64 bit, however, I have encountered problems while running the last (third line) command.

pip install -U pip setuptools wheel
pip install -U spacy
python -m spacy download en_core_web_trf

Error:

INFO: pip is looking at multiple versions of en-core-web-trf to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install en-core-web-trf because these package versions have conflicting dependencies.

The conflict is caused by:
    spacy-transformers 1.1.4 depends on torch>=1.6.0
    spacy-transformers 1.1.3 depends on torch>=1.6.0
    spacy-transformers 1.1.2 depends on torch>=1.6.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Anyone knows how to solve it? thanks! I was stuck here for the whole evening.

Solution

  • Information for someone who will have the same problem with me.

    The mentioned problem was finally not solved, at least I tried to reinstall packages, reinstall python (totally uninstalled it before reinstalling). Nothing worked for me.

    How did I avoid this finally?

    I uninstalled the python completely.

    Install Anaconda (latest version), while installing the Anaconda, the pip and python are also installed by default. Then I use pip install XX in the windows command line, no matter to install spacy, or to install the requirements.txt, all work well. That's how did I avoid the above mentioned problem.

    Hope it is helpful for someone who also have this problem.
