UnicodeDecodeError in ch14_part2.ipynb about python-machine-learning-book-3rd-edition HOT 5 CLOSED

I tried the code as you told, and it caused no errors.
I found following code is also OK.

model_dir = 'models\\autompg-dnnregressor\\')

It was my easy mistake.
I should have replaced '/' with '\' because I am using windows machine...
I am sorry.

Now I can proceed to read the book.
Thank you very much.

Hard to say, but my best guess is that the dataframe was maybe not loaded correctly. Could you check and show a screenshot of how the data frame looks like? E.g., maybe screenshot the output from df.tail() or df.head()

Thank you for your response.
I cannot find any problem in dataframe and csv file.

auto-mpg.csv

Hm, so strange! I mean, it's nice that the dataframe looks ok, but this makes it harder to debug.

Instead of

regressor = tf.estimator.DNNRegressor(
    feature_columns=all_feature_columns,
    hidden_units=[32, 10],
    model_dir='models/autompg-dnnregressor/')

can you change it to

regressor = tf.estimator.DNNRegressor(
    feature_columns=all_feature_columns,
    hidden_units=[32, 10],
    model_dir="regressor")

Glad to hear it worked!
