ERROR: Cannot install nlp-architect==0.3.1, nlp-architect==0.4, nlp-architect==0.4.post1, nlp-architect==0.4.post2, nlp-architect==0.4.post3, nlp-architect==0.5, nlp-architect==0.5.1, nlp-architect==0.5.2, nlp-architect==0.5.3 and nlp-architect==0.5.4 because these package versions have conflicting dependencies.

The conflict is caused by:
    nlp-architect 0.5.4 depends on dynet==2.1
    nlp-architect 0.5.3 depends on tensorflow==1.15.0
    nlp-architect 0.5.2 depends on dynet==2.1
    nlp-architect 0.5.1 depends on dynet==2.1
    nlp-architect 0.5 depends on dynet==2.1
    nlp-architect 0.4.post3 depends on dynet==2.1
    nlp-architect 0.4.post2 depends on dynet==2.0.2
    nlp-architect 0.4.post1 depends on dynet==2.0.2
    nlp-architect 0.4 depends on dynet==2.0.2
    nlp-architect 0.3.1 depends on dynet==2.0.2

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
