When I tried to install the Google Core API package, it always gets errors for every different version of this package. The app is run in Python 3, and I got the following logs:

```
The user requested google-api-core==1.21.0
    google-cloud-core 1.4.3 depends on google-api-core<2.0.0dev and >=1.19.0
    google-api-core[grpc,grpcgcp] 1.29.0 depends on google-api-core 1.29.0

```

```
ERROR: Cannot install -r requirements.txt (line 52) and google-api-core[grpc,grpcgcp]==1.14.0 because these package versions have conflicting dependencies.
ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies

The command '/bin/sh -c pip3 install -r requirements.txt' returned a non-zero code: 1
ERROR
ERROR: build step 0 "gcr.io/cloud-builders/docker" failed: step exited with non-zero status: 1

```

We want to install this package on the Google Cloud Platform.
Could somebody please help me with the conflicting dependency issue?

We tried the following packages but none of them work.

```
