How to use an SSD1603 (oled 0.96'') with Attiny85

Hello where do i find it at? I think i downloaded the correct library. When i try to compile it i get a compile no error. like this.

Sketch uses 4300 bytes (52%) of program storage space. Maximum is 8192 bytes.
Global variables use 190 bytes (37%) of dynamic memory, leaving 322 bytes for local variables. Maximum is 512 bytes.

But when i try to upload it i get this.

avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.

An error occurred while uploading the sketch

I updated the sketch to this.

#include <Arduino.h>
#include <U8g2lib.h>

U8X8_SSD1306_128X64_NONAME_SW_I2C u8x8(7,5,1);
void setup(void) {
u8x8.begin();
}

void loop(void) {
u8x8.setFont(u8x8_font_chroma48medium8_r);
u8x8.drawString(0,0,"Hello World!");
delay(1000);
}

Unless i did something wrong or the library is wrong Which i don't think think so i got the library from. GitHub - olikraus/u8g2: U8glib library for monochrome displays, version 2
