root2hdf5 回溯：tree2rec() 'entries' 得到了一个意外的关键字参数

Question

我安装了rootpy，并确保满足这里列出的root2hdf5的要求。

当试图运行root2hdf5在一个简单的ROOT文件生成以下代码:

void tree1w() {
    // Create a Tree file tree1.root - create the file, the Tree and a few branches
    TFile f("tree1.root", "recreate");
    TTree t1("t1","a simple Tree with simple variables");
    Float_t px, py, pz;
    Double_t random;
    Int_t ev;
    t1.Branch("px", &px, "px/F");
    t1.Branch("py", &py, "py/F");
    t1.Branch("pz", &pz, "pz/F");
    t1.Branch("ev", &ev, "ev/I");
    // Fill the Tree
    for (Int_t i = 0; i < 10000; i++) {
        gRandom->Rannor(px, py);
        pz = px * px + py * py;
        random = gRandom->Rndm();
        ev = i;
        t1.Fill();
    }
    // Save the Tree; the file will be automatically closed
    // when going out of the function scope
    t1.Write();
}

我得到以下错误:

INFO:rootpy.root2hdf5] Converting tree1.root ...
INFO:rootpy.root2hdf5] Will convert 1 tree in this directory
INFO:rootpy.root2hdf5] Converting tree 't1' with 10000 entries ...
Traceback (most recent call last):

TypeError: tree2rec() got an unexpected keyword argument 'entries'

我不太明白为什么我看到这个错误，我将非常感谢任何帮助让这个转换器工作。

安装最新的rootpy。对不起，还没有新的标签，但是当使用较新版本的root_numpy时，您需要安装超过0.7.1版本的rootpy:

git clone git://github.com/rootpy/rootpy.git
cd rootpy; ./setup.py install --user
