Conflicting package versions

[fishbone1]

$ pip install tensorspacejs==0.2.0

(...)

ERROR: Cannot install tensorspacejs because these package versions have conflicting dependencies.

The conflict is caused by:
    keras 2.2.2 depends on keras-applications==1.0.4
    tensorflow 1.12.0 depends on keras-applications>=1.0.6

Without version requirement, pip installs version 0.0.2 which only output "Hello world from converter"
