Hello, I have created project based on “multiple\_kernels” example in Vitis and I have added my own IP something like this:

```
kernel void vecAdd( global double *a,                     
                       global double *b,                      
                       global double *c,                       
                       const unsigned int n,
int ide)                  
{                                                            
    //Get our global thread ID                                  
    int id = get_global_id(0);                                
     ide = id;                                                          
    //Make sure we do not go out of bounds                     
    if (id < n)                                                
        c[id] = a[id] + b[id] + id;                                
} 

```

I have tried to use this .xclbin in Pynq but I’m getting parsing error.  
`ol = Overlay("/media/sd-mmcblk0p1/multi_krnl.xclbin")`

```
    ValueError Traceback (most recent call last)

ValueError: invalid literal for int() with base 10: ''   

```

Any ideas why it is crashing?  
I have created this design with petalinux 2020.2  
[multi\_krnl.zip](https://discuss.pynq.io/uploads/short-url/usDLfr7Bx84P7sVuuontvmKhVQd.zip) (1.0 MB)

- one more question, how can I provide libsensors for Pynq?  
I have tried several times with libsensors in petalinux, but still same error  
/usr/lib/python3.7/site-packages/pynq/pmbus.py:230: UserWarning: Could not initialise libsensors library  
warnings.warn(“Could not initialise libsensors library”)

Thanks 🙂
