ktrain not installing - PEP 517 Error

[samwalkow]

Hi,

I'm trying to install ktrain to my base environment and I get this error:

I'm on a mac mojave OS, python version 3.7.3, and pip3 version 20.0.2. I tried installing it in my terminal and in a jupyter notebook with no luck. I appreciate any help!

Hi there:

Everything works on Linux (and Windows according to users), so it may be a Mac issue. Moreover, it appears to be an issue with the transformers library. See this issue on the transformers GitHub repo, which describes the issue and various proposed solutions.

This post, in particular, describes a solution for Mac users that appears to work based on the number of people who "liked" the post. The post says:

Hi, I had the same problem and resolved it by installing rust.
"error: Can not find Rust compiler"

For MacOS, I used "curl https://sh.rustup.rs -sSf | sh". I also found that it needed a nightly version of rust, so you have to specify that in the install options.

Can you give this a shot to see if it solves the problem?

This solution or this solution may also work based on comments in the thread.

huggingface/transformers#2831 (comment) - this solution worked for me!

I did have some more errors regarding the 'wrapt' library, but I was able upgrade and solve that issue. I still see some tensorflow related errors, but I can still import the ktrain into my jupyter notebook and it seems to be working.

Thanks so much for your help!
