bencode | Bencode parser in c | Parser library

How do we build a simple linear autoencoder and train it using torch.optim optimisers?

How do I do it using autograd (.backward()) and optimising the MSE loss, and then learn the values of the weights and biases in the encoder, and the decoder (ie. 3 parameters in the encoder and 4 in the decoder)? And the data has to be randomized, for each run of learning, start from random weights and biases, such as:

I'm trying to add calendars to Google through a Python script.

Relevant code:

I have been at this most of the day today, so I normally have success with iterations and working with keys/values. This time its not easy easy it seems, running back and forth between the php docs and trailing difference sources, no luck but this is as close as I came.

So in this code, we are checking ../../uploads for all *.torrent files and parsing each one and saving as BLOB => database.

The code works wonderfully, with individual uploads. So I decided to loop it all together and send all of the files to the database based on their DB ID / FILE ID (which all match). So the logic there was easy.

This is the code I have

Why can't we simply convert Clojure code to string and send it over TCP and evaluate on the other side(nrepl)?

For example : This is a hashmap {"foo" "bar", 1 "spam"} whose BENCODE encoding is d3:foo3:bari1e4:spame.

If we convert it to string -> {\"foo\" \"bar\", 1 \"spam\"}

and evaluate on the other side instead of using BENCODE as shown below.

I write a spider ,it handshake and extend handshake is ok,and i success download metadata but when bdecode ,except failnot a valid bencoded string

i receive data like :

How does stack resolve dependecy conflicts?

I just started off with Haskell and I have few questions on how stack resolves dependencies.

1. Let's say my project requires lib A and lib B.

   Internally, lib A requires lib X-1.9.0 and lib B requires lib X-2.0.0, how would stack resolve this?

   stack documentation says they use snapshots to resolve conflicts, how does that work? Does it mean authors of lib A and lib B decide on a version of lib X which works with both of them? If so, what happens when I use a newer version of lib A or lib B or if either of them are not in the snapshots?

   How are snapshots actually made?

2. Stack by default installs packages globally. What happens when a Project A requires lib Y-1.0 and Project B requries lib Y-1.1? How does this gets taken care of?

3. How does one use packages at "stackage.org"?

   I was trying to install beam-core and google took me to https://www.stackage.org/package/beam-core where there's no mention of the command which installs it or what is the latest version. I could not find the version number anywhere expect in github releases.

   With both pip and npm, it's quite straight forward and all the information on how to install and use is available on package's page. For example both,

   https://pypi.org/project/bencode.py/

   https://www.npmjs.com/package/projects

   contains version number and install command, even though they are quite obvious.

4. I often get errors related to 'stack-configuration' when I try to install a package. I don't what 'stack-configuration' is? What does all these errors mean and how to resolve them in context with all the above questions?

Performing stack install beam-core or stack repl --package beam-core --package beam-sqlite --package sqlite-simple --package beam-migrate --package text results in
