I'm trying to run some code using PyPy to speed it up. My code uses Pandas dataframes, so I'm trying to find a way to install the package...
Unfortunately, I can't find a way to do that... searching online yields this and this -- two disappointing results which say it's not possible, but they are 1-2 years old!
There was a glimmer of hope from this twitter post from Romain Guillebert which suggests I could do it using a package called pymetabiosis. Unfortunately when I go to install that, I get the error mentioned below.
Any idea how I can debug the error or find some other way of using Pandas with PyPy?**
