How to set version number of the package imported locally

[Ahmad Ismail]

My `go.mod` file looks like

```

module school

go 1.13

replace sample.com/math => ../math

```

When I run `go run school.go` the `go.mod` file changes to:

```

module school

go 1.13

replace sample.com/math => ../math

require sample.com/math v0.0.0-00010101000000-000000000000 // indirect

````

My question is

1. where does the package gets this version number (in this case v0.0.0-00010101000000-000000000000)?

2. How to set the version number

1. It's a made up dummy

2. You cannot and you need not.
