TypeError: can't create 'SPI' instances,TypeError: can't convert str to int

[qiuxiaochao]

I have 2 problem with the instantiations of the SPI，TypeError: can't create 'SPI' instances,TypeError: can't convert str to int
My ESP32 color screen solution:
Screen driver: ST7789 (MISO=0,MOSI=23, SCK=18, CS=5, DC=7, RST=16)
Touch driver: GT911 (SDA=21, SCL=22, RST=19)

spi_bus=spi_bus,

slider = lv.slider(scrn)
slider.set_size(300, 50)
slider.center()

label = lv.label(scrn)
label.set_text('HELLO WORLD!')
label.align(lv.ALIGN.CENTER, 0, -50)

MPY: soft reboot
Traceback (most recent call last):

TypeError: can't convert str to int

soft reboots are not supported. If you are using thonny then you will need to press the reset button on the ESP32 when you see this error.

[qiuxiaochao]

press the reset button on the ESP32,
it worked,This method works,
but need press several times.

here is my test code,worked.
