I was trying to clean up duplicates in an excel file using dedupe.
The code worked fine at first and the code itself is simple. But whenever I run the code I get the below error. The code works fine if I delete all the temp files, restart pycharm or restart my computer and it won't run for the second time.
The data file is a csv file with a list of random similar name in column A with header as 'Name'. Please help tp resolve. Thank you.
Code
import pandas as pd
import pandas_dedupe
#loading data
df = pd.read_csv('duplicate.csv')
#deduplication process
df_final = pandas_dedupe.dedupe_dataframe(df,['Name'])
#save to csv
df_final.to_csv('cleansed_output.csv')
Getting error below
C:\Users\Username\AppData\Roaming\Python\Python38\site-packages\pandas_dedupe\utility_functions.py:17: FutureWarning: The default value of regex will change from True to False in a future version.
df[i] = df[i].str.replace('[^\w\s\.\-\(\)\,\:\/\\\\]','')

The answer is in the error:
You need to either turn off multiprocessing or protect the calls to the Dedupe methods with a if __name__ == '__main__' in your main module
Change your code to the following, and try again:

#loading data
df = pd.read_csv('duplicate.csv')
#deduplication process
df_final = pandas_dedupe.dedupe_dataframe(df,['Name'])

Thanks for your help in advance.
It looks like tplink_jetstream.py assumes that a (now removed) helper function is available to it. The simplest fix here would be to go into that file and modify the line containing crypto_utils.bit_length(parameters.q) to read parameters.q.bit_length() instead.
I am using the most lightweight/simple dask multiprocessing which is the non-cluster local Client:
from distributed import Client
client = Client()
Even so: the first instance of invoking dask.bag.compute() results in the following:

The result is that you can more or less flip a coin on whether the program will proceed or error out with a communication exception. Here is what happens when the flip comes up "tails":

for event in device.read():
print(event)
There is a problem when I run the code - I get the following error: AttributeError: 'NoneType' object has no attribute 'terminate'
I have also tried to read a single event:
import inputs
while True:
for device in inputs.devices:
event = device.read()
print(event)
This gives me the same error.
I am using Python3.6 and inputs==0.4 from pip
Does anyone know how to fix this error?

RuntimeError:
An attempt has been made to start a new process before the
current process has finished its bootstrapping phase.
This probably means that you are not using fork to start your
child processes and you have forgotten to use the proper idiom
in the main module:
if __name__ == '__main__':
freeze_support()
...
The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce an executable.

Define your steps under a method like:
def func():
while True:
for device in inputs.devices:
event = device.read()
print(event)
And then call your function using:
if __name__ == '__main__':
func()
I have a relatively straight forward snippet which throws an error:
import shutil
abspath_to_source_file = '/media/moose/VFF1147/MAP_DATA/BACK/B0000040.DFT'
target_dir = '/media/moose/9C33-6BBD/PRIVATE/PANA_GRP/PAVC/LUMIX/MAP_DATA/BACK'
shutil.copy2(abspath_to_source_file, target_dir)
which gives

Is the reason eventually be the file system? (If I remember it correctly, I formatted it as exFAT, but I only get 'fuseblk' when I try df -T or mount. sudo file -Ls /dev/sdb1 gives DOS/MBR boot sector)
1st question: What is the problem?
2nd question: How can I fix it?
