问题是，在尝试训练线性回归模型时，我总是会遇到相同的错误吗？我的数据集有问题吗？
训练数据集：https://www.mediafire.com/file/mc1ukij1rp2kkcz/FishTrain.csv/file
用于测试的数据集：https://www.mediafire.com/file/t0a75spn7xc9xsq/FishTest.csv/file
这是我的代码：
import numpy as np
import os
import tensorflow as tf
import matplotlib.pyplot as plt
df_train = pd.read_csv (r"C:\Users\femi0\Desktop\ccc\FishTrain.csv")
df_test = pd.read_csv (r"C:\Users\femi0\Desktop\ccc\FishTest.csv")
y_train = df_train.pop('Weight')
y_test = df_test.pop('Weight')
CATEGORICAL_COLUMNS = ['Species']
NUMERIC_COLUMNS = ['Length1', 'Length2', 'Length3', 'Height', 'Width']
feature_columns = []
for feature_name in CATEGORICAL_COLUMNS:
vocabulary = df_train[feature_name].unique() # gets a list of all unique values from given feature column
feature_columns.append(tf.feature_column.categorical_column_with_vocabulary_list(feature_name, vocabulary))
for feature_name in NUMERIC_COLUMNS:
feature_columns.append(tf.feature_column.numeric_column(feature_name, dtype=tf.float32))
print(df_test.loc[4])
def make_input_fn(data_df, label_df, num_epochs=13, shuffle=True, batch_size=32):
def input_function(): # inner function, this will be returned
ds = tf.data.Dataset.from_tensor_slices((dict(data_df), label_df)) # create tf.data.Dataset object with data and its label
if shuffle:
ds = ds.shuffle(1000) # randomize order of data
ds = ds.batch(batch_size).repeat(num_epochs) # split dataset into batches of 32 and repeat process for number of epochs
return ds # return a batch of the dataset
return input_function # return a function object for use
train_input_fn = make_input_fn(df_train, y_train) # here we will call the input_function that was returned to us to get a dataset object we can feed to the model
eval_input_fn = make_input_fn(df_test, y_test, num_epochs=1, shuffle=False)
linear_est = tf.estimator.LinearClassifier(feature_columns=feature_columns)
linear_est.train(train_input_fn) # train
result = linear_est.evaluate(eval_input_fn) # get model metrics/stats by testing on tetsing data
print(result)
这是错误代码：
