Missing f-string at the error messages in torchvision.utils._parse_colors

[loomlike]

🐛 Describe the bug

At torchvision.utils._parse_colors, the following lines don't use f-string so that the error message prints the literal {colors}, not the value of colors variable.

    607     raise ValueError("`colors` must be a tuple or a string, or a list thereof, but got {colors}.")
    608 elif isinstance(colors, tuple) and len(colors) != 3:
    609     raise ValueError("If passed as tuple, colors should be an RGB triplet, but got {colors}.")
