pandas – MemoryError: Unable to allocate 11.0 GiB for an array with shape (120, 12300000) and data type object

I am trying to read a 40GB file in pandas and perform some operations on it.
I am using chunk, but getting MemoryError.
(RAM of System = 32 GB)


df = pd.DataFrame()
for chunk in pd.read_csv('file.csv',low_memory = False, chunksize = 50000):
    df = df.append(chunk)

How should my code be in order to read the large file ?

ftp – FileZilla and IIS: GnuTLS error -110: The TLS connection was non-properly terminated

I’m trying to connect to a VPS running Windows Server 2019 using Filezilla Client, but get the error

GnuTLS error -110: The TLS connection was non-properly terminated.

My Let’s Encrypt certificate is set for domains:,,
My IIS configuration is set to use this certificate on both the global level (see screenshot 1) and on the FTP level (see screenshot 2).
Screenshot 1
enter image description here
Screenshot 2
enter image description here
My FileZilla settings (using Default transfer mode, but I tried Active and Passive too with the same error)
enter image description here

Resulting in this logging in FileZilla:

Status: Resolving address of
Status: Connecting to
Status: Connection established, waiting for welcome message...
Response:   220 Microsoft FTP Service
Command:    AUTH TLS
Response:   234 AUTH command ok. Expecting TLS Negotiation.
Status: Initializing TLS...
Error:  GnuTLS error -110: The TLS connection was non-properly terminated.
Status: Server did not properly shut down TLS connection
Status: Connection attempt failed with "ECONNABORTED - Connection aborted".
Error:  Could not connect to server

Connecting without SSL
I tried to connect without SSL, so set FileZilla to Use explicit FTP over TLS if available.
And on my VPS I configured it to Allow SSL connections (and not require):
enter image description here
I then get the following notification but I AM able to connect:
enter image description here

My guess is it HAS to do with the certificate, but I don’t know what.
I Googled for the error, and tried some debugging like recommended here and here.

I also tried WinSCP, but still can’t connect, so unlike some sites claim it’s a FileZilla bug, I think I need to look for it on the server. But I’m lost on what to check now.
