undefined: dataframe.LoadFromCSV

[andrewm4894]

When i run the below example to read in a df from a dummy string i get the below errors:

➜  learn-go git:(main) ✗ go run dev.go
# command-line-arguments
./dev.go:21:13: undefined: dataframe.LoadFromCSV
./dev.go:21:65: undefined: dataframe.CSVLoadOptions

package main

import (
    "context"
    "fmt"
    "strings"

    imports "github.com/rocketlaunchr/dataframe-go"
)

func main() {

    csvStr := `colA,colB
    1,"First"
    2,"Second"
    3,"Third"
    4,"Fourth"`

    ctx := context.Background()

    df, err := imports.LoadFromCSV(ctx, strings.NewReader(csvStr), imports.CSVLoadOptions{
        DictateDataType: map[string]interface{}{
            "colA": int64(0),
            "colB": "",
        },
    })

    fmt.Println(err)
    fmt.Println(df)

}

I'm not really sure what i'm doing wrong here. Was trying to use example from this sort of approach: https://github.com/rocketlaunchr/dataframe-go/blob/master/imports/infer_test.go

Here is the output of go env

p.s. i'm new to Go so pretty sure it could be me doing something silly :)

Your CSV string is not valid. In order to make it look nice, you've added tabs/spaces at the start of each line

[pjebs]

Format it to look like the one in example or read from a CSV file

imports "github.com/rocketlaunchr/dataframe-go/imports"

[pjebs]

Import path is not correct

Thank you - working code below:

package main

import (
    "context"
    "fmt"
    "strings"

    imports "github.com/rocketlaunchr/dataframe-go/imports"
)

func main() {

    csvStr := `
colA,colB
1,"First"
2,"Second"
3,"Third"
4,"Fourth"`

    ctx := context.Background()

    df, err := imports.LoadFromCSV(ctx, strings.NewReader(csvStr), imports.CSVLoadOptions{
        DictateDataType: map[string]interface{}{
            "colA": int64(0),
            "colB": "",
        },
    })

    fmt.Println(err)
    fmt.Println(df)

}
