前沿文本生成模型，能够理解文本、进行转换和生成代码。

T1、在线生成代码

Certainly! Here's a prompt in English that you can use to generate Python machine learning code:
"Please create a Python script that implements a machine learning algorithm for classifying iris flowers based on the iris dataset. The script should include steps for data loading, preprocessing, model training, and evaluation using accuracy as the metric. Use a popular machine learning library such as scikit-learn, and provide comments in the code for clarity."

#Import necessary libraries
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.linear_model import LogisticRegression
from sklearn.metrics import accuracy_score

#Load the iris dataset
iris_data = pd.read_csv('iris.csv')

#Preprocess the data
X = iris_data.drop('species', axis=1)
y = iris_data['species']
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

#Train the logistic regression model
model = LogisticRegression()
model.fit(X_train, y_train)

#Evaluate the model
y_pred = model.predict(X_test)
accuracy = accuracy_score(y_test, y_pred)
print('The accuracy of the model is:', accuracy)

T2、采用gemma-7b的API实现

from openai import OpenAI

client = OpenAI(
  base_url = "https://integrate.api.nvidia.com/v1",
  api_key = "$API_KEY_REQUIRED_IF_EXECUTING_OUTSIDE_NGC"
)

completion = client.chat.completions.create(
  model="google/gemma-7b",
  messages=[{"role":"user","content":"who are you?"}],
  temperature=0.5,
  top_p=1,
  max_tokens=1024,
  stream=True
)

for chunk in completion:
  if chunk.choices[0].delta.content is not None:
    print(chunk.choices[0].delta.content, end="")

3、LLAMA2-70B的使用

语言生成

前沿的大型语言人工智能模型，能够根据提示生成文本和代码。

T1、在线生成代码

Please create a Python script that implements a machine learning algorithm for classifying iris flowers based on the iris dataset. The script should include steps for data loading, preprocessing, model training, and evaluation using accuracy as the metric. Use a popular machine learning library such as scikit-learn, and provide comments in the code for clarity.

#Import necessary libraries
from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler
from sklearn.svm import SVC
from sklearn.metrics import accuracy_score

#Load the iris dataset
iris = load_iris()
X = iris.data[:, :2]  #we only take the first two features.
y = iris.target

#Split the dataset into training and testing sets
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

#Scale the data using StandardScaler
scaler = StandardScaler()
X_train_scaled = scaler.fit_transform(X_train)
X_test_scaled = scaler.transform(X_test)

#Train an SVM model on the scaled training data
svm = SVC(kernel='linear', C=1)
svm.fit(X_train_scaled, y_train)

#Evaluate the model on the test data
y_pred = svm.predict(X_test_scaled)
accuracy = accuracy_score(y_test, y_pred)
print(f"Accuracy: {accuracy:.3f}")

#Use the trained model to make predictions on new data
new_data = [[5.1, 3.5]]
new_data = scaler.transform(new_data)
prediction = svm.predict(new_data)
print(f"Prediction: {prediction}")

T2、采用LLAMA2-70B的API实现

from openai import OpenAI

client = OpenAI(
  base_url = "https://integrate.api.nvidia.com/v1",
  api_key = "$API_KEY_REQUIRED_IF_EXECUTING_OUTSIDE_NGC"
)

completion = client.chat.completions.create(
  model="meta/llama2-70b",
  messages=[{"role":"user","content":"Please create a Python script that implements a machine learning algorithm for classifying iris flowers based on the iris dataset. The script should include steps for data loading, preprocessing, model training, and evaluation using accuracy as the metric.

  temperature=0.5,
  top_p=1,
  max_tokens=1024,
  stream=True
)

for chunk in completion:
  if chunk.choices[0].delta.content is not None:
    print(chunk.choices[0].delta.content, end="")
