Hello, @mayankagarwal19911! I'm here to assist you with any bugs, questions, or contributions you may have. Let's tackle this issue together!
To resolve the InvalidLLMOutputType: Response validation failed!
error and successfully generate the schema using pandasai 2.2.8 and Python 3.9.6, follow these steps:
Ensure the Template Correctly Specifies the Expected Output Type:
Modify the template in pandasai/prompts/templates/correct_output_type_error_prompt.tmpl
to ensure it specifies the expected output type.
{% for df in context.dfs %}{% set index = loop.index %}{% include 'shared/dataframe.tmpl' with context %}{% endfor %}
The user asked the following question:
{{context.memory.get_conversation()}}
You generated this python code:
{{code}}
Fix the python code above and return the new python code but the result type should be: {{output_type}}
Set the Correct Output Type in Your Context:
Ensure that the output_type
variable is correctly set to the expected type in your context. For example, if you expect a DataFrame, output_type
should be set to DataFrame
.
from jinja2 import Template
template_str = """
{% for df in context.dfs %}{% set index = loop.index %}{% include 'shared/dataframe.tmpl' with context %}{% endfor %}
The user asked the following question:
{{context.memory.get_conversation()}}
You generated this python code:
{{code}}
Fix the python code above and return the new python code but the result type should be: {{output_type}}
"""
context = {
'dfs': [df], # Your DataFrame
'memory': memory, # Your conversation memory
'code': generated_code, # The generated Python code
'output_type': 'DataFrame' # The expected output type
}
template = Template(template_str)
corrected_code = template.render(context=context)
print(corrected_code)
Handle Validation in call_llm_with_prompt
Method:
Ensure that the call_llm_with_prompt
method in your BaseAgent
class correctly handles the validation of the output type. The method should retry the prompt if the validation fails.
def call_llm_with_prompt(self, prompt: BasePrompt):
retry_count = 0
while retry_count < self.context.config.max_retries:
try:
result: str = self.context.config.llm.call(prompt)
if prompt.validate(result):
return result
else:
raise InvalidLLMOutputType("Response validation failed!")
except Exception:
if (
not self.context.config.use_error_correction_framework
or retry_count >= self.context.config.max_retries - 1
):
raise
retry_count += 1
Generate and Validate the Schema:
Ensure that the schema generation and validation are correctly implemented in the SemanticAgent
class.
def _create_schema(self):
if self._schema:
self.logger.log(f"using user provided schema: {self._schema}")
return
key = self._get_schema_cache_key()
if self.config.enable_cache:
value = self._schema_cache.get(key)
if value is not None:
self._schema = json.loads(value)
self.logger.log(f"using schema: {self._schema}")
return
prompt = GenerateDFSchemaPrompt(context=self.context)
result = self.call_llm_with_prompt(prompt)
self.logger.log(f"Initializing Schema: {result}")
self._schema = result.replace("# SAMPLE SCHEMA", "")
schema_data = extract_json_from_json_str(result.replace("# SAMPLE SCHEMA", ""))
if isinstance(schema_data, dict):
schema_data = [schema_data]
self._schema = schema_data
if self.config.enable_cache:
self._schema_cache.set(key, json.dumps(self._schema))
self.logger.log(f"using schema: {self._schema}")
Ensure Correct Output Type Validation:
Ensure that your generated code produces a result dictionary with the correct type
and value
fields that match the expected output type.
class DataFrameOutputType(BaseOutputType):
@property
def template_hint(self):
return """type (must be "dataframe"), value must be pd.DataFrame or pd.Series. Example: { "type": "dataframe", "value": pd.DataFrame({...}) }"""
@property
def name(self):
return "dataframe"
def _validate_value(self, actual_value: Any) -> bool:
return bool(df_type(actual_value))
By following these steps, you should be able to resolve the InvalidLLMOutputType: Response validation failed!
error and successfully generate the schema [1][2][3][4].

@pratik9409 sure, thanks a lot for the availability, I've assigned it to you! :D
df = pd.DataFrame(columns=["Empdata"], data=[[1], [2]])
df.head()
try:

# Print the generated schema
print(semantic_agent._schema)
except InvalidLLMOutputType as e:
print(f"Error: {e}") # Print the error message
print("Using fallback schema...") # Inform the user that a fallback schema will be used
