Hi, as shown in the following full dependency graph of biopipe, biopipe requires urllib3 >=1.22 , while the installed version of requests(2.22.0) requires urllib3 <1.26,>=1.21.1.
According to Pip's “first found wins” installation strategy, urllib3 1.25.7 is the actually installed version.
Although the first found package version urllib3 1.25.7 just satisfies the later dependency constraint (urllib3 <1.26,>=1.21.1), it will lead to a build failure once developers release a newer version of urllib3.
