INFO: pip is looking at multiple versions of eznlp to determine which version is compatible with other requirements. This could take a while. ERROR: Cannot install eznlp and eznlp==0.2.0 because these package versions have conflicting dependencies.

The conflict is caused by: eznlp 0.2.0 depends on transformers==4.3.2 allennlp 2.0.1 depends on transformers<4.3 and >=4.1

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

This issue is the conflict of versions between allennlp and transformers.

From scratch, you may first install pytorch and torchvision by conda like:

$ conda install pytorch==1.7.1 torchvision==0.8.2 torchtext==0.8.1 -c pytorch

Then manually install the following packages:

$ pip install flair==0.7
$ pip install allennlp==2.0.1
$ pip install transformers==4.3.2
$ pip install jieba==0.42.1
$ pip install hanziconv==0.3.2
$ pip install truecase==0.0.12
$ pip install openpyxl
$ pip install pandas 
$ pip install eznlp --no-deps
