I am trying to install eif package, used for extended isolation forest algorithm, but the installation is failing. I get this error on trying pip install eif or pip install git+https://github.com/sahandha/eif.git:

How can I install the library properly?

  • @phd I solved the issue by installing a previous version of eif: pip install eif==1.0.2 . I think the problem is with the newest version. – Library System Dec 14 '19 at 12:58

    The difference is that [`eif`==1.0.2](https://github.com/sahandha/eif/tree/755488507ce8f507fe1f12dcf7d730813431557c) is pure Python so you can install it without a C/C++ compiler while [`eif`==2.0.2](https://github.com/sahandha/eif/tree/b50f8081df06e5f692bfbb9e7d7937a10f37ccc4) has code written in Cython and converted to C++ so you need a compiler for it. It's not a "problem", you just need a compiler. The compiler for w32 is M$ VC. – phd Dec 14 '19 at 13:55
