安装python,numpy,scipy和theano到〜/ .local之后,我试图导入theano,但它引发了一个错误:
>>> import theano
Problem occurred during compilation with the command line below:

collect2: ld returned …我正在使用Hadoop 1.0.4的"新"API(包org.apache.hadoop.mapreduce中的类).当我想链映射器/缩减器时,我发现ChainMapper,ChainReducer是为"旧"API(包org.apache.hadoop.mapred中的类)编写的.我该怎么办？
