This could take a while. ERROR: Cannot install -r tmp_requirements.txt (line 3), -r tmp_requirements.txt (line 7) and -r tmp_requirements.txt (line 8) because these package versions have conflicting dependencies.

The conflict is caused by: matplotlib 3.4.3 depends on numpy>=1.16 mkl-fft 1.3.1 depends on numpy<1.23.0 and >=1.22.3 mkl-random 1.2.2 depends on numpy<1.25.0 and >=1.24.3

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
