Based on work in https://github.com/pandas-dev/pandas/pull/39226
I tried `asv continuous -f 1.1 -E virtualenv upstream/master HEAD -b strings` but got

> · Unknown commit upstream/master

Would be good to add a hint to [the docs](https://pandas.pydata.org/docs/development/contributing_codebase.html#running-the-performance-test-suite) to run `git fetch upstream master` in that case.

Also, the following hint in `asv_bench/asv.conf.json` appears to be wrong:

> // The Pythons you'd like to test against.  If not provided, defaults
    // to the current version of Python used to run `asv`.
    // "pythons": ["2.7", "3.4"],
    "pythons": ["3.8"],

I got an error

> · No executable found for python 3.8
· No environments selected

Changing to `"3.9"` and rerunning, I get this error

Does the Python interpreter have to be in a clean virtualenv or something like that? I think I need some help here fixing this error:

``` @jreback 3 tests timed out after 60 min. Is that equivalent to 'green' or anything still to do? thanks @janosh very nice!

and @erfannariman for the original!
