I keep getting this error:

Depending on what disFile represents in your case, this should do the trick:
joinFile = os.path.join("disFile", "Sales_Data_2020")
According to the error I guess that disFile on your end represents a list which won't work. Thus, you would have to select a string of that list to join it.

I try to web-scrap the news data using beautiful soup getting a Nonetype attribute error.
Error:

AttributeError: 'NoneType' object has no attribute 'text'
The expression link.find("strong") returned None,
as the HTML contained no matches.
You need to test for that, perhaps with an if statement,
so you only ask for .text in situations where in fact it exists.
I tried to saved a model like the official code of transformer on official website, but when i want to save the train_step graph or trace on it with tf.summary.trace_on ,it errors.the error is as

I supposed it was some error on tensor operation and write an other demo to confirm my idea:
import tensorflow as tf
sig=[tf.TensorSpec(shape=(None, None), dtype=tf.int64),tf.TensorSpec(shape=(None, None), dtype=tf.int64)]
#tf.function(input_signature=sig)
def cal(a,d):
b=a[1:]
root=tf.Module()
root.func = cal
# 获取具体函数。
concrete_func = root.func.get_concrete_function(
tf.TensorSpec(shape=(None, None), dtype=tf.int64),tf.TensorSpec(shape=(None, None), dtype=tf.int64)
)
tf.saved_model.save(root, '/correct', concrete_func)
the error occurs as supposed. But how can i fixed it? the positional_encoding requires and i have no idea about how to replace this operation.
I figure it because i didn't save the transformer model in the pb file
I'm reading the book-python crash course. I'm using python3.
in chapter 16, there is code like this:
import csv
filename = '/Users/pc/Desktop/CS
Book/Python_crash_course_practice/16.1/sitka_weather_07-2014.csv'
with open(filename) as f:
reader = csv.reader(f)
header_row = next(reader)
print(header_row)
but it doesn't work, and gave me an error as below. I don't know how to solve it. Is there someone can help me? thanks.

There are non-ASCII characters in your file, so you need to specify the file encoding on reading.
You can also add this in the first line of your python script, to set utf-8 as default encoding
#!/usr/bin/env python # -*- coding: utf-8 -*-
Although this is my first attempt at using pexpect, the python3 script using pexpect is pretty simple; yet it fails.
#!/usr/bin/env python3
import sys
import pexpect
SSH_NEWKEY = r'Are you sure you want to continue connecting \(yes/no\)\?'
child = pexpect.spawn("ssh -i /user/aws/key.pem ec2-user#xxx.xxx.xxx.xxx date")
i = child.expect( [ pexpect.TIMEOUT, SSH_NEWKEY )
if i == 1:
child.sendline('yes')
print(child.before)
The SSH_NEWKEY is the only response I'm expecting, but the example showed a list containing pexpect.TIMEOUT in it so I used it.

An EOF error is being raised during your expect call. This means that the response received does not match SSH_NEWKEY, and reaches end of file within the timeout period. To catch this exception, you should change your except line to read:
i = child.expect( [ pexpect.TIMEOUT, SSH_NEWKEY, pexpect.EOF)
You can then make your if more robust:
if i == 1:
child.sendline('yes')
elif i == 0:
print "Timeout"
elif i == 2:
print "EOF"
print(child.before)
This doesn't solve the reason behind why you are on receiving a response with the expected string - it's hard to know without looking at more code but it's likely because you have the response slightly wrong. If you manually type in the SSH string, you should be able to see the response you can expect, and enter this response into your code.
You can also print child.before after your expect call, or print child.read() instead of your expect call to see what is being sent back as a response.

comment 1:we did remap_tablespace because we wrongly put the schema on system tablespace,
comment 2:we run this code on one computer and it worked but it is not working on other computer
Please guide me...
It seems the datamining user does not exist. Please create it and retry the import.
Thanks
