I can’t open file.

my code is fault ?

```python
# Hello World Example
#
# Welcome to the OpenMV IDE! Click on the green run arrow button below to run the script!

import sensor, image, time

sensor.reset() # Reset and initialize the sensor.
sensor.set_pixformat(sensor.GRAYSCALE) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.VGA) # Set frame size to QVGA (320x240)
sensor.skip_frames(time = 2000) # Wait for settings take effect.
clock = time.clock() # Create a clock object to track the FPS.

while(True):
    for i in range(10):
        clock.tick() # Update the FPS clock.
        img = sensor.snapshot() # Take a picture and return the image.
        print(clock.fps()) # Note: OpenMV Cam runs about half as fast when connected
                                    # to the IDE. The FPS should increase once disconnected.
        img.save("b-pra-b-05-"+ str(i) + ".bmp")
        
        sensor.reset() 
        
        img2 = image.Image( "/ b-pra-b-05-1-05.bmp")
        

        # image.b_and(b-pra-b-05-1.bmp[mask = b-pra-b-05-1-05.bmp])

    break

```
