error, No mask_token (mask) found on the input

Hi @XiaotianHe ,
Thank you for your interest in our work!
The mask token is

Uri

< m a s k >

But remove the spaces 😀

Can you give me a complete sample input?

I tried input text "Encryption algorithm AES [Uri]" and still got the same error.

Here is a sample output:

while (<mask>) {

Best,
Uri

I would like to have a sample input, not output, to retrieve a complete java code from your model. Such as "Encryption algorithm AES [Uri]" or "Encryption algorithm AES

I would like to have a sample input, not output, to retrieve a complete java code for a specified algorithm from your model. Such as "Encryption algorithm AES (mask)". So I can see a complete set of java code to get AES implemented.

Sorry, I meant "a sample input". while (<mask>) { is a sample input.

But this model was not designed to "retrieve a complete java code" so I'm not sure what do you mean.

For retrieving code snippets and documentation, see our another project DocPrompting: https://github.com/shuyanzhou/docprompting

How would this help me in java coding? I thought your model is supposed to help with java programming.

No :-)

this model is designed for java code similarity.

For java programming, see https://github.com/VHellendoorn/Code-LMs which is available on huggingface as this model: https://huggingface.co/NinedayWang/PolyCoder-2.7B

Best,

Uri,

I looked into the model NinedayWang/PolyCoder-2.7B, I still could not get a useful java code. Here is my input and output:

Input: Give me a Java code for Encryption algorithm AES-256
Output: [{"generated_text":"Give me a Java code for Encryption algorithm AES-256.\n "}]

Do you know how to get some useful source codes?

Thanks
Xiaotian

That model was trained on code completion, so I expect it to work better if you gave it the beginning of the code, for example the function signature, and then your request as a javadoc.

Can you give me an example?

Yes, please see: https://github.com/VHellendoorn/Code-LMs#october-2022---polycoder-is-available-on-huggingface

Thanks for sharing. I read it carefully, but still cannot find a sample input. Can you please simply share a sample input that leads to generating a useful java code?

For Polycoder? Here is a sample input:

def binarySearch(arr, left, right, x):
    mid = (left +

I got following result by running your sample input:

[{"generated_text":"def binarySearch(arr, left, right, x):\r\n mid = (left + right"}]

It only adds "right", and does not generate a complete code at all. Is that what I am supposed to see?

By running following input:
def binarySearch(arr, left, right, x):
mid = (left +

I got following output:
[{"generated_text":"def binarySearch(arr, left, right, x): mid = (left + right"}]

By running following input:
def binarySearch(arr, left, right, x):
mid = (left +

I got following output:
[{"generated_text":"def binarySearch(arr, left, right, x): mid = (left + right"}]

By running following input:
def binarySearch(arr, left, right, x):
mid = (left +

I got following output:
[{"generated_text":"def binarySearch(arr, left, right, x): mid = (left + right"}]

Hi @XiagotianHe,

I just ran the PolyCoder model using the exact code here: https://github.com/VHellendoorn/Code-LMs#october-2022---polycoder-is-available-on-huggingface and got following 4 completions:

def binarySearch(arr, left, right, x):
    mid = (left + right) // 2
    if arr[mid] == x:
        return mid

def binarySearch(arr, left, right, x):
    mid = (left + right) // 2
    if arr[mid] > x:
        return binarySearch(arr

def binarySearch(arr, left, right, x):
    mid = (left + right) // 2
    if arr[mid] < x:
        return -1

def binarySearch(arr, left, right, x):
    mid = (left + right) / 2
    if arr[mid] > x:
        return binarySearch(arr

How did you run it? Where is this json that you pasted coming from?

{"inputs":"def binarySearch(arr, left, right, x): mid = (left +"}

This is not our code and I cannot support it. We just released the model, and we demonstrate that the model works. I hope you understand

How about the input json? Does it look correct?
{"inputs":"def binarySearch(arr, left, right, x): mid = (left +"}

If it wouldn't have looked correct to me I wouldn't have provided it to you :-)
The only difference between this and the input I provided you is a newline character after the function signature.
