I am trying to install flair. It is throwing below error when executing below command:

pip install flair

ERROR: Packages installed from PyPI cannot depend on packages which are not also hosted on PyPI.
tiny-tokenizer depends on SudachiDict_core@ https://object-storage.tyo2.conoha.io/v1/nc_2520839e1f9641b08211a5c85243124a/sudachi/SudachiDict_core-20190927.tar.gz

I thought installing this package explicitly might fix the error but it doesn't. The error remains same. The installed version of SudachiDict-core is below: SudachiDict-core 0.0.0

Below is the Environment:

  • OS: Windows 10
  • Python: 3.6 (64 bit)

Any hint is appreciated. Thank you!

Note:

  • First hurdle when installing flair was torch package. It was resolved simply when torch package is installed. The error looked like below: ERROR: Could not find a version that satisfies the requirement torch>=1.1.0 (from flair) (from verERROR: No matching distribution found for torch>=1.1.0 (from flair)

You can try

pip install --upgrade git+https://github.com/zalandoresearch/flair.git

Source: https://github.com/flairNLP/flair/issues/1327#issuecomment-571639994

Or

to install separately:

pip install tiny-tokenizer

After this run:

pip install flair

  • Perhaps the command based on the latest flair repository should be: `pip install --upgrade git+https://github.com/flairNLP/flair.git` – SillyQuestion Jan 04 '23 at 10:34

It is strange running below command solved the problem.

pip install flair==0.4.3

I assume that the problem is in a latest version 0.4.4 (and its dependencies).

Note: I had torch==1.1.0 package already installed.
