chembl_webresource_客户端在google colab上安装失败

Question

需要您的帮助，我尝试在colab上安装chembl_webresource_客户端，它通常工作正常，但今天让我惊讶的是，在第一步就出现了错误

!！pip安装chembl_webresource_客户端#安装客户端

from chembl_webresource_client.new_client import new_client # here is where is wrong
molecule = new_client.molecule
res = molecule.search('viagra')


---------------------------------------------------------------------------

      2 molecule = new_client.molecule
