Deal with the error 'Reached the maximum number of allowed errors' - wolfma61/CNTK GitHub Wiki
The CNTKTextFormatReader can tolerate a maxErrors number of malformed lines (default is 0). The error message
Reached the maximum number of allowed errors while reading the input file
means that that the reader has encountered more than maxErrors malformed lines. Make sure you have generated the input file correctly (e.g. there are no stray vertical bars in comment streams (|#)) or increase maxErrors if recreating the input file is close to impossible.
