python – conda environment conflict: guesslang and TensorFlow

when I run conda env create -f environment.yml in my ubuntu 20.04, but conflict occurs.
how can I solve it?

I try to update my anaconda, but it doesn’t go well

The conflict is caused by:
    guesslang 2.2.1 depends on tensorflow==2.5.0
    guesslang 2.2.0 depends on tensorflow==2.5.0
    guesslang 2.0.3 depends on tensorflow==2.5.0
    guesslang 2.0.1 depends on tensorflow==2.2.0
    guesslang 2.0.0 depends on tensorflow==2.2.0

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
